Binompdf & Binomcdf (TI83/84 calculator)

[johnricarte33]

for some reason i thought this was hilarious. but you got the job done. thank you sir.

[dduble07]

Thanks man, saved my grade for tomorrow.

[HenkieRS]

Thanks so much ! one video explains this better than my bs school book.

[ThePhilmeeks]

Ah at last someone who can teach math in english!

[appleormac]

Thank you! I will give you money when I get a well paying job!

[shannon32121]

You are a life saver!!!! I love you!



[MoMMessEh]

You can do the regular thing, 1-binomcdf(100,.8,79) or if you have already computed binomcdf(100,.8,79), you enter 1 then shift to find the ans key and enter that.

[ronaldrayers]

How did you input 1-ans?

[TheNorthEestern]

Awesomeness.

[uberrrich]

wowwww, put so simply! thank you! i have a test in 20 minutes lol

[makidude]

I think a better way to end his video is explain how to deal with problems pertaining with "at least" 80. In which case, you subtract 1 less from the desirable outcome that you want. For example, What is the success rate of getting at least 80 shots? it goes: 1-binomcdf(100,.8,79) What he meant by "more than" 80 can be translated as "at least" 81 shots. >_>

@makidude I needed this....thanks!



[iRateUrClips]

[Mr1Flux]

You just helped me pass my exam!

[Gieltjeuh]

Thanks alot, I totally get it now :)

[ToobsRiderRM]

[ronald7795]

helped me out alot



[mdbreda]

this teacher is a stats BOSS

[dawnswe]

OMG, it's that simple! Thanks for making this great video just what i needed for my test tomorrow :)

[blueandmax]

This video helped me so much, thanks a bunch. Really good explanation!

[laceyjulian]

thanks this is amazing

[gamrshaque]

i think you just saved me a failing grade in my statistics class

[xFennaa]

Thanks! It helped alot!

pdf stands for probability distribution function and calculates individual probabilities.

Example: binompdf(3,.5) gives .125 .375 .375 .125

These are the probabilities of 0,1,2 or 3 successes with n=3 and p=0.5.

cdf stands for cumulative probabilities.

Example: binomcdf(3,.5,2)  Gives the probability that we have 0, 1, or 2 successes added together, so we get .125 +.375 + .375 = .875

[KiddyBrucie15]

I'm mainly confused on the wording of things and when to use pdf or cdf. Geometric we basically find a number of successes with an indefinite number of trials, while a bimodial we're given a set number of trials, right?

When do we use pdf or cdf in either cases? I tend to mess up on hw with those and I was wondering if there was a way to identify which one in the context of a question. Similar to how we see "and" as multiplication and "or" as addition in probabilities.

[benjiimaster]

Also..... das war total einfach! Vielen Dank fuer dieses Video!

[UFOJeroen]

thanks dude

[komala3]

I'm taking a stat course online. I never noticed the difference between the

binomcdf and bionompdf functions. THANKS

[hellzbomber]

brilliant lesson! exceptional, you clarify the material to such a degree it's amazing.

Many thanks

[Basz112]

could be my teacher pls?:D thnx alot

[Dug1423]

I was looking at my friends notes since I had a test the next day and had noo idea what the heck binompdf ment!!! Or where to find it on my calc. This made my night! Thanks for making this vid :)

[liz110]

woa, thanx! I have my math exams tomorrow and I forgot how it worked, now I remember!

[melodyhovsepian]

HELPFUL!!

[MeddizzleMan]

i have an ap stat exam tomorrow. this video saved me! thx

[centerhalf39]

Thanks. That definitely helped.

[criscris73]

that is great thanks! One question, I get results in this format: 99.300211481e-3 but would like to have results in decimal like you, what setting is this please? Thanks

[MoMMessEh]

@criscris73 Your answer is in decimal form using scientific notation. The e-3 on the end of the number means to shift the decimal point 3 places to the left so 99.300211481 e-3 becomes 0.099300211481.

[MoMMessEh]

@criscris73 to get a true decimal presentation, hit the mode button and highlight normal and enter. That will get you in normal decimal load.

[isard99]

I whish I had that teacher...

Even it it means math in english and not in german but that worth it xD

[MoMMessEh]

@isard99

Danke isard99. Herr Professor Messenger ist der Lehrer. Ich bin Professor Ehlers und wir beide arbeiten so das Mathematik leicht und erfreulich ist.

[martijnsfeestclub]

it took my teacher two year to teach my this.

it took you 3 and a half minute and i get it completly now so thank you verry verry much!

[basdingen]
