Stats: Binomial Probability Distribution (Part 2)

[@xbsoft]

No! You're not wasting time at all.. Please continue your best way of explaining it. You're very helpful and for some way you make it very easy to comprehend. Thank You!

[@michaeltipsword3398]

Just spent the last couple hours watching all your videos and taking notes. They were all very helpful, well put together, excellent explanations on everything. You explain this subject better than any teacher I have ever had. Thanks.

[@OFTwify]

I've been stuck on a problem for more than an hour and it was just... just n=10, P=0.5... exactly, more than, less than and at least 2... You made this so much more simple. I even tried to "free tutor" program and here I am learning more on youtube.

[@Mytosha]

The way my teacher explained this really stressed me out, but you made is seem so simple. Thank you for the video!

[@JasonOon]

you didnt even use the formula...

[@cammie3679]

omyghaddd thank youuu this really helped me. infact, i understand your explanation more than my teacher's explanation thank youuu

[@bhyteme]

This video literally saved my ass thank you so much! My prof gave us questions like these without ever once going through a single one that was like them

[@Nxo-mq7py]

AH I used the formula and it was so long but I cross checked with the table and it was correct. Thank you for this this method !!! Way easier and saves me so much time.

[@Queenslassie]

cant we solve it without using a table? we dont have a table, and thats frustrating

[@giggitygoobrick]

Yes, he gave you an equation in the first video.

[@ichimori88]

You most probably already took ur test, but for those asking the same question, you can just also use (nCx)(p^x)(q^n-x) this is the same except the whole factorial thingy is replaced with nCx.

[@tshifhiwathovhakale9385]

Lily Shamanova what does C mean on the nCx

[@petrikor4411]

combination n!/n!x!

[@miankamran5700]

it's too nice sir i m easy now after takes ur helpful lecture MAY ALLAH KAREEM blessed u always with sweet moments

[@gdl30]

This is very cliche in tutorial videos, but you explained it better than my teacher. Thank you.

[@brandilibby4541]

Thank you for giving such a clear and understandable explanation. I wish I had found your videos at the beginning of the semester. Look forward to looking at other videos from you while studying for my exams. Thank you so much!

[@rsloveeeee]

u da best. cramming for my stats test lol.

[@joejoeOnlyOneJoe]

im cramming one hour before the exam :D

[@herbertorellana4089]

I am cramming 4 hours before the exam, never been to class!

[@suleimanfikere8667]

roxylove and

[@kangwagershom4632]

Am cramming 2 hours before my Stats test today!

[@Perex221]

goodluck on your test! lol

[@lazarusmkr]

God bless you you saved my ass from failing that stats exam

[@poysermath]

Depending on your textbook, if np < 5 or if nq < 5, then you CANNOT use the method described in this video. That is, if your sample size is too small, then you cannot approximate a binomial distribution with a normal distribution.

[@alexisviciedo9349]

Thank you but what do you do afterwards

[@muzammilsabah3135]

Very good way of explaining I'm a M.Phill student and facing a little difficulty in understanding these terms thnx a lot for explaining it soo nicely :)

[@moodymoonlight3909]

Thanks so much!! this helped me on my final exams :D you sir are a life saver

[@mahmouduthman8955]

Thank you very much for your contribution sir. But please we'd like you to continue with the next(part 3)

[@sheanagray2436]

Thank You sooooooooo much my professor could not even break the wording down like that! I love you :)

[@poysermath]

Hi Nerdyman01, "fewer than" means "less than". So, "fewer than 8" means "less than 8". And less than 8 is P(0) + P(1) + P(2) + ... + P(6) + P(7), but does not include P(8). Let's say you had to find "more than 7" which means P(8) + P(9) + ...up to P(n). Then in this case, you could find "fewer than 8" and subtract the result from 1. That's using the Complement Rule. Hope that makes sense.

[@EricCKeys]

Thanks much for the clear understanding. A big help with my stat101 homework!

[@kelseyy1993]

Thank you so much! I was so confused and now it makes so much sense!

[@kategurtowsky]

It would be helpful to complete the equation

[@EEnrighteousAyusoyolo]

studying this for my exam.. u made it simple . to understand thanks

[@shaywhite]

great videos - huge help! Thank you!

[@moriaha4877]

Awesome explanations!!! Thank you for the help!

[@sydneebarker4395]

Thank you so much! This video is so helpful! :)

[@aishalepionnier6952]

you’re the best i hope you can come and teach my dr how to teach

[@ksinglet86]

this has helped me so much! thank you!!!

[@manoclocknews]

Dear Sir, there is a formula used to calculate each probability, which you do not mention here, the table is nice and all, but there is a way of calculating without. why didn't you show that?

if u dnt have the table use the formula: P(x) =nCx (p^x) (q^n-x) ... you'll find *nCx* on your calculator

[@severerevenge8575]

What about this one2≤X≤8It would be good example

[@riverwing7497]

Do we use binomial pdf or cdf?

[@jeanquinto9171]

you should've show us how to solve it w/out the table so that we can compare our answer to yours and check it if were doing it right, nice video btw.

[@makedamartin9655]

this video help me a lot. however my teacher in the part for few than 8 he included the figure 8. he had me a little confused at this point. thanks a lot for clearing this for me. cud u do other terms such as "exactly" and "at least".

[@user-xq3jq3cf2f]

can you calculate without the table please

[@stevesensei5727]

Thanks for your help big man

[@b3llasam139]

OMG! you are such a life saver,,thanks alot, xoxoxoox

[@betlow9497]

Thank you very very much for your clear explanation. I got it now.

[@moonfanaras]

so what happens if you get a question that says "all"? My stats homework has "probability that she gets ALL 9 serves?"

[@asms7735]

its quite helpful. thanks a lot ! :D

[@Josh-do4ln]

So without the table I have to do the formula for each individual one? There’s got to be a better way to do this.

[@udemeachiuwa9640]

Thank you so much. This was extremely helpful

[@brianj.3274]

Great stuff Mate...Thanks. B

[@elleinad1719]

this helped so much!

[@litbriteLUVzU]

How do you do the math without using the table? Is there a way? I do not have a table. So I want to know if there is another way to do all of this without one.

[@StevenFornicola]

What about when a probability isn't an even .20, .30., etc.

[@tshifhiwathovhakale9385]

igot tht,ive been struggling wth maths,but what if the table is not given,does that mean im going to do all those probabilities,or there is a simpler way?

[@IrisPark98]

wish you wrote the answers for each so I know for sure Im doing this right on my calculator but thanks

[@alankota797]

How would I use that binomial table if my probability is 0.39?

[@rebelliousbynature99]

Thank you, this helped a lot

[@Nerdyman01]

If its "fewer than", don't you have to subtract the probability from 1? Example, (1 - answer) = the probability.

[@annettekosterman3191]

omg thank you so much!!! this video is very helpful :)

[@satwindersingh2570]

Thanks you have solved my problem

[@emmanuel3929]

what if probability exceeds 0.5

[@aisha16xox]

What if the product of nq and np are less than 5? how would you do that? please help!

[@piyushcom]

nicely explained.. thank you

[@itsnotmeitsyou4582]

I’m lost at where does .05 come from 1-13?

[@tramdhan111]

I still don't understand why you get (.157) in the table for n=13 k=8 and p=0.5. What I see in my table the result is (.8666)

[@poysermath]

We have different tables. Your table shows an accumulation of k values up to 8. In other words, your table shows you (n = 13,k = 0,p = 0.5) + (n = 13,k = 1,p = 0.5) + (n = 13,k = 2,p = 0.5) + etc... all the way up to (n = 13,k = 8,p = 0.5). So, using your table, to find the value for ONLY (n = 13,k = 8,p = 0.5)...without the accumulation of prior x-values, you will simply do the following: (n = 13,k = 8,p = 0.5) - (n = 13,k = 7,p = 0.5). These values are: .8666 - .7095 = .1571 My table does not accumulate prior x-values, like your table does.

[@EEnrighteousAyusoyolo]

+poysermath Hey i have the same table that has accumulation so when your looking for P(0) ... in my table is the answer i find that or do i have to subtract p(0) from something?

[@anassaburass]

Man you're awesome. Thanks!

[@trudy161able]

hw would you put X=0 or 2 or 4 as a probability? Need help Plz !

[@lokhilmital3928]

Please ans for a marmalade distribution Q1=24 and mean =37.find qaartile deviation,meas divination.

[@chynx293]

thanks

[@siddharthvipul]

thankyou very much sir.

[@deepakamarlapudi3869]

wait don't you do 1-P(X

[@rickaa1957]

Good but do you solve by hand if don't have the table?

[@NajeelovesGod3]

+jericka barker use the formula from the first video

[@rickaa1957]

okay thanks

[@BakerFarajat2]

Thank you!

[@scarney29]

Strange. My book has table that goes from n=12 then skips to n=15! Good video though thank you.

[@JosSerrano11]

Men.. thank you very much!

[@growingwiththewades8093]

It would've been much more helpful if you showed how to find the probabilities of the numbers instead of referring to a chart

[@poysermath]

But showing you how to find probabilities involves calculus, which most of my students haven't taken yet. So, instead, we use Tables, graphing calculators, or statistical software to find probabilities for us. It's much faster, and does not require knowledge of higher math.

[@helenkennedy332]

Thank you

[@feliciagcaba-nongawuza9590]

Clear explanation. But can't you explain without referring to the table which we don't have.

[@fa9eelh]

use the equation he tells in the first video. we just plug in the values basically and let the calculator do the rest of the job.

[@abdullahiibrahim8103]

Thnks alot

[@4040hassan]

thank u so much dude u r really great teacher

[@cameronjordan897]

2 or more?

[@23dexedc]

thx!! awesome1

[@emmakunkel9374]

We know what ‘at most’ and ‘at least’ mean... I wanted to learn about binomial distribution, not greater than and less than.

[@rjm5080]

There's a part 1 of this video...

[@NeoSpacian1237]

thankk yo u!

[@manoclocknews]

P(X) = N!/X!(N-X)! * P to the power of X * (1-P) to the power of N-X thats the formula, using it you don't need a table. (like in the test)

[@herowise6021]

patrickjmt??

[@el6700]

Yes but I don’t get to use a chart in my exam lol

[@fa9eelh]

memorize the formula

[@dylandruce]

no audio?

[@breannad.5632]

this is not helpful your not telling us what to do afterwards, this was a waste of my time

[@greyveil5343]

thaaaaaaaaaaaaaank yooooooouuuu

[@SantosM.V.C]

Pkkkkkk

[@sadafbenaf]

Described superbly!

[@attacusgreens]

You waste too much time
