The Multinomial Theorem. October 9, 2008. Pascal's Formula. Multinomial coefficient: ( n n1,n2,,nt) = n! n1!n2! ···nt! , where n1 + n2 + ··· + nt = n. Binomial coefficients are a particular case of multinomial coefficients: (nk) = ( n k, n ? k). Theorem 1 (Pascal's Formula for multinomial coefficients.) For integers n, n1,n2,,nt.
21 Dec 2017 Full-text (PDF) | In this note we give an alternate proof of the multinomial theorem using a probabilistic approach. Although the multinomial theorem is basically a combinatorial result, our proof may be simpler for a student familiar with only basic probability concepts.
UDE, Fakultat fur Mathematik: Discrete Mathematics (C1) [Multinomial coefficients]. 1 The result is given by the "multinomial coefficients": ( n m1,, Alternative proof. The second expression for the multinomial coefficients suggests the following idea: Build all per- mutations from X, fill the boxes following the permutation.

402 CHAPTER 4. SOME COUNTING PROBLEMS; MULTINOMIAL COEFFICIENTS. If A is a finite set with n elements, we mentioned earlier. (without proof) that A has n! permutations, where the factorial function, n > n! (n ? N), is given recursively by: 0! = 1. (n +1)! = (n + 1)n!. The reader should check that the existence of

16 Feb 2011 1 Multi-sets and multinomial coefficients. A multinomial coefficient is associated with each (finite) multiset taken from the set of natural numbers. Such a multi-set is given by a list k1,,kn, where . The proof is the following. Consider an n element set with multi-index N having values given by the integer
The above is called the multinomial coefficient. We will use an informal proof for this theorem. Definition Given a set with n elements, consider a multiset of type a1,a2,,ak with a1,a2,ak ?. 0 and ? k i="1" ai = n to be a partitioning of of the set in k parts, part i having ai elements, respectively, for all i. Note that we have
4 Aug 2016 Introduction. The multinomial theorem is an important result with many applications in mathematical statistics and computing. It expands (x1 +x2 ++xm)n, for integer n ? 0, into the sum of the products of integer powers of real numbers x1,x2,,xm. The prevalent proofs of the multinomial theorem are either
