I am very much interested whether there are Probability Distribution Questions on GMAT. If yes what types they are: Hypergeometric Probability Distribution; Binomial Probability Distribution; Poisson Probability Distribution or other.

For people who canтАЩt remember exactly which type what kind of questions include, here you are some ideas:

A Hypergeometric Probability Distribution Problem:

An urn contains fifteen balls, five red and ten green. What is the probability of obtaining exactly two red and three green balls in drawing five balls without replacement?

A Binomial Probability Distribution Problem:

A coin is tossed five times. (This is the same as a sample size of five). What is the probability of obtaining exactly two heads in the five tosses?

A Poisson Probability Distribution Problem:

In manufacturing the Que model car, a study determined that on average there are three defects per car. What is the probability of buying a Que with less than three defects?

If somebody of you has encountered such problems, please let us know. Probably, it will be useful to tell us also your Math score or at least the Overall.

Thanks all of you.

I am sure Gravedigger will be glad to share his thoughts on this :D

I have met only this kind:

A Hypergeometric Probability Distribution Problem:

#12 or 13; I missed it and the problems got easier. I got 49 eventually.
