The hypergeometric distribution is used for sampling without replacement. The density of this distribution with parameters m, n and k (named Np, N-Np, and n, respectively in the reference below) is given by. p(x) = choose(m, x) choose(n, k-x) / choose(m+n, k) for x = 0, â¦, k.
If and in such a way that, then the binomial distribution converges to the Poisson distribution with mean. Let and be independent binomial random variables characterized by parameters and. The conditional probability of given that is. (66). Note that this is a hypergeometric distribution.
