The hypergeometric distribution is a discrete distribution where we consider the number of successes over the number of trials without any replacement. Such a type of distribution is useful in cases where we need to find the probability of something without replacing it.
Let us say we have a bag full of red and green balls and we have to find the probability of picking a green ball in 5 attempts but each time we pick a ball, we do not return it back to the bag. This is an apt example of the hypergeometric distribution.
