About the Hypergeometric Distribution
The hypergeometric distribution is a discrete probability distribution that describes the probability of X successes occurring in n draws, without replacement from a finite population size N, with exactly K success states, where each draw can either be a success or a failure. The hypergeometric distribution differs from the binomial distribution, describing the probability of k successes in n draws with replacement.
