Hypergeometric Distribution

Hypergeometric distribution is a probability distribution that is based on a sequence of events or acts that are considered dependent. Compare this to the binomial distribution, which produces probability statistics based on independent events. Imagine that there is an urn, with fifty colored balls in it. Twelve of them are blue, and the other 38 are red. You're planning to take ten balls out, without looking, and without putting them back in between draws.
