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.
The key difference between the binomial and hypergeometric distribution is that with the hypergeometric distribution Select one: a. the probability of success must be less than 0.5 b. the random variable is continuous c. the probability of success changes from trial to trial d. the trials are independent of each other
