Multinomial Coefficients | Brilliant Math & Science Wiki

Multinomial coefficients are generalizations of binomial coefficients, with a similar combinatorial interpretation. They are the coefficients of terms in the expansion of a power of a multinomial, in the multinomial theorem. The multinomial coefficient, like the binomial coefficient, has several combinatorial interpretations. This example has a different solution using the multinomial theorem; see that wiki for details. The multinomial coefficients are the coefficients of the terms in the expansion of ...
