The hypergeometric distribution is a discrete distribution bounded by [0,s]. It describes the number of defects, x, in a sample of size s from a population of size N which has m total defects. The ratio of m/N = p is sometimes used rather than m to describe the probability of a defect.
The hypergeometric distribution is used to describe sampling from a population where an estimate of the total number of defects is desired. It has also been used to estimate the total population of species from a tagged subset. However, estimates of all three parameters from a data set are notoriously fickle and error prone, so use of these parameters to estimate a physical quantity without specifying at least one of the parameters is not recommended.
