Hypergeometric distribution is a random variable of a hypergeometric probability distribution. Using the formula of you can find out almost all statistical measures such as mean, standard deviation, variance etc.
Where,
N: The number of items in the population.
n: The number of items in the sample.
x: The number of items in the sample that are classified as successes.
P(x| N, n, k): hypergeometric probability – the probability that an n-trial hypergeometric experiment results in exactly x successes, when the population consists of
\(\begin{array}{l}N\end{array} \)
items, \(\begin{array}{l}k\end{array} \)
of which are classified as successes.
Solved Examples
Question 1: Calculate the probability density function of the hypergeometric function if N, n and m are 50, 10 and 5 respectively ?
Solution:
Given parameters are,
N = 50
n = 10
m = 5
Formula for hypergeometric distribution is,
P(x|N,m,n) = 
P(x|N,m,n) = 
So, the probability distribution function is,
P(x|50, 5, 10) =
