Hypergeometric distribution is used to test probabilities for dependent trials.

Use Hypergeometric Distribution when you are sampling without replacement.

Describes the probability of successes in draws *without* replacement from a finite population of size containing exactly successes.

This is in contrast to the binomial distribution, which describes the probability of successes in draws *when sampling with* replacement.
