WebC(m + n, r) = C(m, r – k) C(n, k) •Proof (by combinatorial arguments): To select r items from m + n distinct objects, we may assume that among these objects, m are white and n are black. The selection may start by selecting k black objects, and then the remaining from white objects. As k can vary from 0 to r, this gives the result. WebSuppose we have n distinct items and wish to select k of them and place them in order. We say we are permuting k out of n items, or just \n permute k". The total number of possibilities is: P(n;k) = n! (n k)! Note 2.2.1. This is sometimes denoted nPk. Note 2.2.2. If we’re permuting all of them then k = n and this is just n!. 2.3 Basic ...
