Hypergeometric Distribution

A hypergeometric distribution is the probability distribution of a hypergeometric random variable .

The hypergeometric distribution is defined by the following formula:

Hypergeometric Formula. Suppose a population consists of N items, k of which are successes. And a random sample drawn from that population consists on n items, x of which are successes. Then the hypergeometric probability is:

h(x; N, n, k) = [ kCx ] [ N-kCn-x ] / [ N Cn ]

where kCx is the combination of k things taken x at a time.
