Binomial Distribution - Cumulative Probability Tables : ExamSolutions

[@salemrostom]

wow ... i was like 12 hours trying to understand this and i couldnt and now in 8 minutes understood everything ... Thats crazy ...
no more classes haha just youtube ans specially you sir...
thank u so much

[@ExamSolutions_Maths]

+Salem Rostom Thanks for using.

[@EpicEditsBySaz]

Sir, seriously, this video really helped me loads. Thank you.

[@ExamSolutions_Maths]

Good.

[@_trm_4339]

Where are you now sadeq

[@Vayanovic]

you are a GENIUS! never thought i would be able to figure out how to understand this,from SCRATCH in just a matter of minutes! Keep em tutorials coming! this is brillant! I shall let my friends know about this :D

[@ayodejidaramola3238]

U just saved a life

[@ExamSolutions_Maths]

+Ayodeji Daramola TYhat's what I like to hear

[@peaceandloveonthisplanetea6564]

Thank you, you make statistics seem somewhat less boring

[@sustantivo1espritu]

OMG I WISH I HAD FOUND YOUR CHANNEL EARLIER!! I have an examtoday on quantitative methods and its a few hours more and this is what i learnt. THANK you ill sub you as a form of my gratitude

[@101orbitaldefence]

Thank you so much, you have explained what a textbook and teacher cannot.

[@galibkhan4418]

wow, thats crazy simple. I always get stuck at the stupid sign crap, but you did an excellent job

[@ExamSolutions_Maths]

@tehboxface You use an approximation depending on the values of n and p. If np>5 and nq>5 we use a Normal approximation.

[@nabilahnoh1705]

you save my life sir thank you so much. Im aiming for B after watching this cause i always get E for my statistics.

[@ExamSolutions_Maths]

Go for it. Best wishes.

[@SARMYRO]

This helps a lot! You explained it a lot better than my professor.
You use cumulative binomial table if the questions have "more than, less than etc."
How about inclusively or exclusively?
Thanks

[@yassarhijazi2928]

thank you so much for your help it helped me a lot it makes me wanna cry

[@muryamyousaf9053]

you are great . hero of math.

[@harsh0811]

YOU'RE A GIFT FROM GOD

[@ExamSolutions_Maths]

Thanks

[@odhinrazanga7715]

thanks a lot sir
. this tutorial helps a lot to me.

[@ExamSolutions_Maths]

That's good. Thanks for watching

@Vayanovic thanks

[@jacksowerby9928]

saved my life thank you

[@ExamSolutions_Maths]

Thanks for watching and best wishes at this time

[@yzdani1]

Cheers mate - quite helpful.

[@MEGIDIOT]

You should be a maths book editor. The books in the market do not explain things as easily as you do.

[@Larcen157]

very useful,thanks a lot

this is great help, thank you

[@oshadaattanayake515]

thank you sir.. thank you very very much..

[@ExamSolutions_Maths]

You are very welcome. Thanks for watching.

@sustantivo1espritu Hope it goes well for you. Welcome aboard.

[@awethugomba5746]

Fantastic!

[@100milliseconds]

Thanks a lot!

[@ExamSolutions_Maths]

Cheers

[@tehboxface]

@ExamSolutions oh nice, thanks!

[@ExamSolutions_Maths]

@MEGIDIOT Thank you

[@tehboxface]

hey, your videos are really good. Although, in one of my exams the n value was over 20. Does that mean i cannot use the binomial table? Because if i dont use it, it would take too long and seeing as its only a 3 mark question- it got me confused. If there is a way, please tell me
thanks

[@ExamSolutions_Maths]

@SARMYRO Sorry, I thought I had explained this in the video.

[@ExamSolutions_Maths]

Use the normal approximation - see my videos on this

[@avilatorresvanessa]

Hello, i really like the video it is very helpful, yet i think that x cannot equal 5 since there are inly 5 trials, from 0-4.
thanks again

[@Idet1000]

+vanea2016 Why not? x=5 would be 5 trials where all five are a success

[@ExamSolutions_Maths]

@DARV2121 Use the formula

[@nrnoornnour2440]

big like

[@RB3565]

oh my days, a bear hug, bruv

[@mohamadhoseinhp]

how can i calculate the following :
my table shows p(x ≥ x) . n=5 , n=10 , n=20 ... and the probability goes until 0.50.
however the question ask me to :
(n=10 , p= 0.75 , x=8 )

[@yzdani1]

Mate - how do you address the following. 200 chances, probability of 60 or fewer successes. Probability of success is 37%.

[@jameswood7207]

For P(X=2) I tried to use the formula but got a different answer (I got 0.131)

[@thecatcher51]

I had the exact same thing! Except i had a guy professor lol. This actually makes sense.

[@TheKarate10]

What do you do if.. shock horror.. n is large and p>0.5? I don't know how to solve that conundrum ):

[@ExamSolutions_Maths]

Frederick This may help you www.examsolutions.net/maths-revision/statistics/discrete-random-variables/binomial-distribution/cumulative-tables/tutorial-2.php

[@DARV2121]

how would you find a probability using the chart if it was .7 probability.... In other words its not exact in your chart. Please help

[@alrayyaniQtr]

can i write F(x) instead?

[@ExamSolutions_Maths]

+alrayyaniQtr I see no reason why not. F(x)=P(X

[@alrayyaniQtr]

ExamSolutions thanks

[@LONEstudios]

@fergbond
Gee, this sounds awkward

[@brandonvestra]

*"Easy"*

[@ddesilva9976]

how do we workout the probability of something like P(6

[@fergbond]

I want to have your children. OMFG thanks.

[@Clavelle12]

Excellent! Many thanks.

[@ExamSolutions_Maths]

Thanks
