Here is how the Hypergeometric Distribution equation looks like.

0.0442 = \frac{C (5, 3) \cdot C (50 - 5, 10 - 3)}{C (50, 10)}

0.0442 = \frac{C (5, 3) \cdot C (50 - 5, 10 - 3)}{C (50, 10)}

0.0442 = \frac{C (5, 3) \cdot C (50 - 5, 10 - 3)}{C (50, 10)}

How to Evaluate Hypergeometric Distribution?

Hypergeometric Distribution evaluator uses Hypergeometric Probability Distribution Function = (C(Number of Items in Sample,Number of Successes in Sample)*C(Number of Items in Population-Number of Items in Sample,Number of Successes in Population-Number of Successes in Sample))/(C(Number of Items in Population,Number of Successes in Population)) to evaluate the Hypergeometric Probability Distribution Function, The Hypergeometric Distribution formula is defined as the probability of obtaining a specific number of successes in a sample drawn without replacement from a finite population, where each element is classified into one of two categories (success or failure). Hypergeometric Probability Distribution Function is denoted by P_{Hypergeometric} symbol.

How to evaluate Hypergeometric Distribution using this online evaluator? To use this online evaluator for Hypergeometric Distribution, enter Number of Items in Sample (m_Sample), Number of Successes in Sample (x_Sample), Number of Items in Population (N_Population) & Number of Successes in Population (n_Population) and hit the calculate button.

FAQs on Hypergeometric Distribution

What is the formula to find Hypergeometric Distribution?

The formula of Hypergeometric Distribution is expressed as Hypergeometric Probability Distribution Function = (C(Number of Items in Sample,Number of Successes in Sample)*C(Number of Items in Population-Number of Items in Sample,Number of Successes in Population-Number of Successes in Sample))/(C(Number of Items in Population,Number of Successes in Population)). Here is an example- 0.044177 = (C(5,3)*C(50-5,10-3))/(C(50,10)).

How to calculate Hypergeometric Distribution?

With Number of Items in Sample (m_Sample), Number of Successes in Sample (x_Sample), Number of Items in Population (N_Population) & Number of Successes in Population (n_Population) we can find Hypergeometric Distribution using the formula - Hypergeometric Probability Distribution Function = (C(Number of Items in Sample,Number of Successes in Sample)*C(Number of Items in Population-Number of Items in Sample,Number of Successes in Population-Number of Successes in Sample))/(C(Number of Items in Population,Number of Successes in Population)). This formula also uses Binomial Coefficient (C) function(s).
