Witrynais useful when sampling without replacement resulting in the probability of success changing each trial. The hypergeometric probability function is used to compute the? the probability that in a random selection of n elements, selected without replacement, we obtain x elements labeled success and n − x elements labeled failure. WitrynaHyperGeometric Distribution Consider an urn with w white balls and b black balls. We draw n balls out of the urn at random without replacement. Let X be the number of white balls in the sample. Then X is said to have the Hypergeometric distribution with parameters w, b, and n X ∼HyperGeometric(w,b,n) Figure 1:Hypergeometric story.

WitrynaThe hypergeometric distribution describes the number of successes in a sequence of n trials from a finite population without replacement. At first glance, it might seem that this is a purely academic distribution, but there are actually many different applications of the hypergeometric distribution in real life.
