MultinomialDistribution

MultinomialDistribution[n,{p1,p2,…,pm}] represents a multinomial distribution with n trials and probabilities pi.

Examples

Create a multinomial distribution:

dist = MultinomialDistribution[10, {0.2, 0.3, 0.5}]

Compute the mean:

Mean[MultinomialDistribution[10, {0.2, 0.3, 0.5}]]
(* {2, 3, 5} *)
