Hypergeometric Probability Distribution

A hypergeometric probability distribution is a probability distribution whose probability values generally conform to a hypergeometric probability function.

• AKA: Hypergeometric Distribution.

  • HYPERGEOMETRIC DISTRIBUTION: Envision a collection of n objects sampled (at random and without replacement) from a population of size N, where r denotes the size of Class 1 and N − r denotes the size of Class 2. Let X denote the number of objects in the sample that belong to Class 1. Then, X has a hypergeometric distribution, written X Hyper(N, n, r), where
    • N = total number of objects
    • r = number of the 1st class (e.g., ”success”)
    • N − r = number of the 2nd class (e.g., ”failure”)
    • n = number of objects sampled.
