 Rachel N. 0 0 The mean of a hypergeometric random variable
 Jahidul I. 0 0 The probability distribution of a hypergeometric random variable is called a hypergeometric distribution. This lesson describes how hypergeometric random variables, hypergeometric experiments, hypergeometric probability, and the hypergeometric distribution are all related. Notation The following notation is helpful, when we talk about hypergeometric distributions and hypergeometric probability. N: The number of items in the population. k: The number of items in the population that are classified as successes. n: The number of items in the sample. x: The number of items in the sample that are classified as successes. kCx: The number of combinations of k things, taken x at a time. h(x; N, n, k): hypergeometric probability - the probability that an n-trial hypergeometric experiment results in exactly x successes, when the population consists of N items, k of which are classified as successes.
