Bonus question is phrased a bit fuzzy. AS ASKED, the answer is 4. the first 4 balls drawn *could* be the same color. But I assume he means "What's the minimum number of balls you must draw at random to BE CERTAIN to have four same colored balls drawn?" Then the worst-case scenario is where you draw 3 of each before getting a 4th, thus 13 balls total.

never over complicate a question like that, it's the easiest way to get it wrong. The phrasing of the question is important, it only asks for the minimum amount needed to draw 4, the answer would be 4, the question never says that you have to be certain you will get 4 of the same colour.

[@MLWJ1993]

#9 can be done this way as well: Cut horizontal, Cut vertical, Put the pieces directly on top of each other and cut in half again. Since no one said I couldn't move the pieces 😂

[@brandyndaigneault1758]

To beat this KZbinr's logic, it's actually impossible for us to cut 8 equal pieces, because anything produced by human means will have a margin of error, thus the impossibility of properly dividing the cake in 8.

Yeah for questions that require such precisely exact language such as question 1, some of the wording is pretty vague and imprecise.

It depends on whether you interpret the question as: "What is the minimum number of balls go get guaranteed 4 of the same color", or "What is the minimum number of balls to have a chance of getting 4 of the same color".

[@sahilpatil9957]

You are telling about maximum number of balls. The question is minimum, so the answer is 4.

[@DarkVoidIII]

@@sahilpatil9957 No, the question asked them to be *drawn at random*. If drawn at random, any colored ball could come out. And he could get the following sequence red, black, green, blue repeated 4 times, before he got a 4th ball of any of the 4 colors in the bag! 4 x 3 ball of each color = 12, so you should understand properly that the problem is randomness of the draw. This could be shown by writing a computer program to randomly draw balls until it got 4 of the same color. It's also algorithmically sound. It is possible that the 13th ball will have to be drawn before guaranteeing a 4th color of one of the 4 colored balls in the bag, and this is what the question was asking: how many minimum would they have to draw, in the worst case randomness scenario.

The last question depends on what you are looking: Least number of balls to have 4 of the same colour is 4. But depending on the colour statistics vary. To ensure you get 4 balls of the same colour is 13. By the 12th picked ball worst scenario you have 3 balls of each colour, the number 13th makes you get the 4th desired ball.

That door numbers one was ridiculous though because we need an 'a' or 'the' to have the question make actual sense.

The First Riddle is Misleading because there is Several Methods of understanding this. Option A: Divide by Half means Divide by Half of the Number which would be 15 thus bringing the Result down to 2+12 which come to 14. Option B: Divide by Half means Divide by Half of One. Which would be 0.5 and thus result in 60 + 12 for 72. Option C: Divide by Half means to Divide it INTO Half which would be 2 and thus bring the Result to 15+12 which would be 27. So this is a Trap Riddle. Because whatever Answer your Opposite Chooses you can just Claim its meant Differently and thus change the Result.

[@madisynfischer947]

If you read it like a Math Formula. Half is 0.5 and you get the Answer chosen here. If you read it like a Sentence in Conversation. Half means to just cut it into half. And if you read it as a Wordplay Half means Half of the aforementioned number. and as Half is lacking any specification here. All 3 can be claimed as right.

Shaking my head at the mansplaining going on here. No one says divide by "half of one". A mathematician would say divide by "one half" which can be shortened to just "half". Your Option A is nonsensical. Your Option C confuses the prepositions "by" and "into"; they're not interchangeable. Yes, you can argue it's deliberately misleading, but that's the point: it's a riddle. It deliberately causes most people to interpret the question as "divide into half" as may be used in casual conversation, but if you look at it logically there was no ambiguity and the answer was obvious.

There is so much sloppy use of basic maths language today that many people end up talking complete nonsense but being understood by people who are used to hearing(and internally translating that nonsense into something that adds up e.g. "House no1 costs 100K.The cost of house no2 is 5 times less." - utter jibberish i.e the second house costs -400K! 1 time less = 100K less i.e. zero,etc. I'm sure one doesn't need to be an unscrupulous conman or marketing rookie to abuse fractions in a misleading way :-)

I feel like the term 'half' used here is a relative term. The 'half' appears to be referring to the 30. Half of 30 is 15. 30 divided by 15 is 2, plus 12 equals 14. This question is almost more about semantics than it is logic.

[@davilinkicefire]

I had a similar reflexion. I didn't like the way the question was formatted. I was like "Divide 30 by half.... by half what ? By the half of 30 ? half of 30 is 15, so 30 divided by its half (15) would mean that is 2 and i add 12 so the answer is 14. But maybe they mean half of ... 1 so 0.5, in that case 30 divided by 0.5 is 60 and i add 12 so the answer is 72... so the answer is 14 or 72, but the question is not really clear"

Question 1 uses English improperly so the question itself is flawed. The correct way to ask the question is, "30 divided by ONE HALF." Native English speakers will automatically infer that "half" means half of whatever the subject is, in this case the number 30. The correct response to question 1 is another question, "30 divided by half of what?" I'd say that this is more a trick English question than a math problem. If I used this question in an interview, I would be most impressed with the people who responded with questions to clarify and not at all impressed with anyone who gave me a number answer.

[@LOGICALLYYOURS]

I must admit that your comment is 100% valid. Specially the last sentence.

[@Vearru]

While grammatically the question might be invalid mathematically it most definitely is valid. When saying you’re dividing something by something you know that that something is a number or representative of a number. Also saying, half while not completely conventional isn’t going to be misunderstood, and in a somewhat conventional way objectively means 1/2. The reason why it makes sense is because 1 is the multiplicative identity (when multiplying anything by it the value will remain unchanged) when you leave a value blank in a multiplicative context it is reasonable to assume it is 1. Of course half implies n/2 regardless of what n is. Therefore by stating you are dividing something by half it implies you are dividing by /2 which in this context would look like 30/ /2 +12 and that clearly means 30*2+12 (it is common knowledge that dividing by a fraction is simply multiplying by it’s inverse). Unless you are looking at a purely mathematical job though the best answer to that question is definitely asking for clarification.

[@catboymothman2495]

For the bonus riddle, the answer is four balls would be the minimum that is needed to be drawn to get four of the same color. The reason is that you could theoretically be extremely lucky and get all of the first four as the same color. The probability of this event is not as high as drawing out different colored balls, but it is not zero, so it is a situation that exists and must be considered.

[@sunilsharma6880]

The ans to the asked question in last is 13 and 4 can also be but 4 is about probability. Otherwise 13 gives 100% chance! It's because when you are finished taking out 12 balls and still there are no 4 same balls then the balls taken out are sure to be 3 each. The 13th ball will complete any one of the 4 pairs.

[@osmanshaikh1987]

[@LOGICALLYYOURS]

Hi Dear.... in the context of puzzle the use of the word "minimum" means "minimum number of objects/attempts to guarantee that something is achieved". With just 4 ball you can't guarantee that all will be same colored.... But if you take out 13th ball, it's going to guarantee us that we get at least four same colored balls...

Bonus Question: minimum number “needed” to get 4 balls of the same color is 4, as even though the odds of doing this are small, they are never zero. The minimum number guaranteed to draw 4 of the same color is 13, as even if you get one of each color 3 different times, the last one will complete a set of 4 no matter what. Then there’s the mathematical way to figure out the average number of draws it would take to obtain 4 of one color, but that’s too long to type here and I really don’t feel like doing that work right now.

The MAXIMUM (not minimum) number guaranteed to draw 4 of the same color is 13

[@ChoirFan1]

It’s a deliberately ambiguous question. Depending on how one interprets “divide 30 by half”....it could be read as any of the following, without being incorrect.... “divide 30 by half (of 30)” ...30/15 ; “divide 30 by (a) half ... 30/.5. ; “ divide 30 (in) half “ ...30/2. There’s a big difference between asking tricky questions and asking trick questions.

[@Da_Infamous]

But your missing the point of why words mean what they mean... half is a .5 and two means well 2 means 2

[@susanacastroegas6375]

Thought so too

[@Bech285]

Actually, by half means half of the original amount, so the correct answer can only be 14. If it had said by one half, 72 would be correct. Sometimes videos can be wrong aswell :D

[@varaprasadbandaru3916]

9/10 done 😉👍

[@jodelparane537]

Divide 30 by half and ads 12 What do you get Me: number?

[@ahriatteimami4541]

I got 14

[@bradevans7107]

Ok...the minimum number of balls drawn at random to get 4 same colored balls ? 7 red 6 green 5 black 4 blue Answer: 4 Explanation: well, assuming the probability of drawing 4 of the same color balls is completely against you, It would take as much as 13 balls drawn. Assuming the probability is completely on your side it would a as little as 4 balls drawn.

[@suryaghosh2226]

Brad Evans no answer is 13 U can't apply probability here

[@SDdubstep104]

Why 13? I got 19, thinking you could draw all the reds then all the greens then all the blacks and finally a single blue. Low odds but I think 19 is a guarantee

[@satyaganesh7159]

Bonus riddle ans: If we pick atleast 13 balls .. We can guarantee that there will be 4 same colored balls

[@ramyajitroy6491]

Please explain others. I also commented the and but I am feeling it difficult to explain to others.

[@satyaganesh7159]

@@ramyajitroy6491 we are required to pick 4 same colored balls, if we pick 12 balls in worst case we might end up in picking 3 same colored balls ie, 3 same colored balls * 4 =12, so to cross this worst case we need to pick 1 additional ball to gurantee that there will atleast 4 same colored balls.

[@xxnonamexx4689]

This is true, but it asked what the minimum number of balls was. So 4 would be correct. If you drew 4 of the same color balls right after eachother, that would be the minimum number of balls that would need to be drawed to have 4 of the same color balls. 13 is the maximum, not the minimum.

[@shivamjain3999]

@@xxnonamexx4689 we are taking the balls at random so there is not a guarantee that we will get 4 balls of same color however if we take a minimum of 13 balls we would definitely get 4 balls of same color.

[@xxnonamexx4689]

@@shivamjain3999, but it said what was the least amount of balls that you would be able to draw to get 4 of the same color balls. It didn't say what number was garenteed. In other words it said what is the least amount of balls needed to get 4 of the same color balls. The least number of balls that need to be drawn to get 4 of the same color of balls is 4.

I´m thirty, have neither a job nor a girlfriend nor any other significant social enviroment, i got non of these riddles right and still watch the video on loop, while i´m listening to this donny darko mad world song and getting hammered at five in the morning. Really i gotta change something x)

[@lowhplowhp]

For number 9 you could also stack the four on top of each other, then cut down through all of them.

[@rubenmedina6883]

Answer to final riddle is 13. The highest number where there's a chance that no color might be picked 4 times is 12: 4 colors, so if each is picked 3 times, you get 12. If you pick 13 balls, then at the very least 1 color will be picked 4 times.

[@SpartyTime]

The answer is 4. Because the question is poorly worded. It didn't say what was the minimum number to guarantee that you would get 4 matching when drawing at random. It asked was is the minimum possible. ;)

[@honolulublues5548]

Don't get all statistical on it. The whole point of these riddles is that the simplistic answer is usually the right answer if you read the question properly.

[@murarichaudhary1454]

Answer for the bonus riddle is 13, Consider worst case when each pick gives u different color ball,after 12 balls u have 3 color of each ,when u pick 13 ball it will match one of the color ball giving u the count 4.

[@rishikgarg2673]

They asked minimum

[@murarichaudhary1454]

This answer is for worst case minimum and for best case minimum the answer is 4 ,when each pick gives u same color.

[@poonams2740]

Yep that's correct

[@ajitbiswal3775]

The ans is 13. The phrase ‘must pick’ itself means the worst case scenario.

[@user-uq1fq6gs3i]

Ajit Biswal / No it doesn’t. Where is your logic at??

[@fatcat5602]

7:20 cut through middle, stack the pieces, cut in half again, stack, and cut again. Eight equal pieces that also look normal served.

[@legendhero-eu1lc]

Thank you for the video! All of you friends are super awesome!

[@gayathria2631]

Is the ans 4?? The question is about minimum no. Of times not maximum..

[@TheSohan1]

4 can be the answer but that is based on luck. I think it should be 16.

[@LimbDee]

I think 4 too, it's a bit of a trick question. If you by chance pick 4 of the same colour in a row you're done. When the question would have been differently formulated, like "what's the maximum amount of blind picks you will have to make to get four balls if the same colour?", the answer would be 13, because after 12 picks there would still be a chance that you would have 3 balls of each colour, but the 13th pick would make one set of 4 complete.

[@shubhamjain7454]

The question do contain a word 'RANDOM' and u have to ENSURE 4 of same colour. So, 13 is the only answer.

[@LimbDee]

@@shubhamjain7454 you don't have to ensure, what makes you think that? Let me try another question on you; what is the minimum amount of random lottery tickets you will have to buy to win the lottery?

[@shubhamjain7454]

@LimbDee : All of them (if winner is going to be only one)

[@Manju........444]

*A fact😊*. We can write 4 by using 3 match sticks like *\lv\* {Roman numbers}

[@Raghav_Rai]

You can also get 8 peices in 9th riddle by first making 4 peices (by horizontal and vertical cuts) and then arrange them in straight line and then make 4th cut which divers them equally in 8 parts..

[@krishnanandprabhu7780]

0:36 What if we interchange the number?🤔
