[@bigbadboz1]

Very useful, learnt more then than I did with my tutor waffling on about it for 3 hours confusing the class more than explaining. Thankyou

[@ProperZing]

Probability of Sam being a Bit of a Dreader = highly likely (or 4/5)

[@GojoSaturu-n1i]

This is helping me with a math test

[@theyareinthetrees6643]

Same, 7:45 and the test is at 8:45 🫡

[@princesskunis]

Thank you so much sir, this video was really helpful🎉🎉❤

[@1stClassMaths]

Most welcome!

[@b4dtz-m1z]

Got nationals tmr and i learnt this with no volume on at 0.75 speed great explanation

[@PeachandMario]

5:10 What if there are what probability of he takes the counter 6 times?

[@dzung1969]

Can you make a video on 3-way venn diagram algebraic type please? Thx

[@1stClassMaths]

I will put it on the really big list I have :)

[@SHIRASSHIHAB]

CLEARLY EXPLAINED WITH EXAMPLES

[@itsgiselle]

​@@mmmzy7043YES OMG HELP ME

[@banana9nnn]

great!!! awesome stuff , thank you ! :3

[@clarizzafernandes8917]

Well explained

[@Horror-cuts254]

why are there two pass n fail 10:27 for English n one for maths?

[@1stClassMaths]

This is because we need to consider all the possible options. The top part of the branch is passing maths but then after this you could pass or fail English. The bottom part is fail maths then you could pass or fail English.

[@Barathraj-bba]

very good examples

[@thembamsibi-q1v]

Clear explanation thank you ..

[@1stClassMaths]

Glad it was helpful!

[@Gimroose]

thank you, it was a clear video. but in the last question, they didnt said that she would lose if she rolled an odd number

[@EvelinaAinyangala]

15:36 I'm very sure the answer for P(not 5,odd)is 7/12.

[@1stClassMaths]

Hi. I am very sure the answer is 15/36 If you explain to me why you think this I can try and explain for you.

[@Kangaroo.kangaroo]

In the “find the probability one of the counters is red why did you not use the path of red and red?

[@1stClassMaths]

Because that would be two reds, not one.

[@Kangaroo.kangaroo]

@@1stClassMaths ohhh I didn’t realise it was that kind of question I don’t think I read it right, thank you

[@hargold-k]

Help me Bag A contains 10 marbles of which 2 are red and 8 are black. Bag B contains 12 marbles of which 4 are red and 8 are black. A marble is drawn at random from each bag. 1. Draw a tree diagram to show all the outcomes of the experiments. 2. Find the probability of getting a red marble and a black marble.

[@dzung1969]

👍

[@shwethamanju1]

In the Lauren problem the not 5 outcome is wrong it should to P(even)=3/5 and P(odd)=2/5. Please explain

[@1stClassMaths]

So you're telling me I am wrong and also asking me to explain?

[@JuniorUziogon.Uz23]

I don't think we can take the five off the dice...yeah we rolled "Not 5" but it's still a probability that we could get a 5 on the second roll so that's why it's still P(even)=3/6 and P(odd)= 3/6

[@dianabarbu7607]

Why are using 5 squares?

[@MikeChikohomero]

Because

[@KhonyaneKhabele]

Please make a video on logarithms

[@1stClassMaths]

[@klosaid50]

answer 13 a) for this topic says 40/360 is 2/9 when it is 1/9 was wondering if that was a mistake or if im just confused?

[@1stClassMaths]

You are correct! I will go and fix this now. Thank you for letting me know.

[@vocco3010]

13 (b) is the answer not supposed to be 722.50? I dont know where the 32/81 came from.

[@1stClassMaths]

Yeah sorry fixed it now.
