WebThe PERMUTATION FORMULA The number of permutations of n objects taken r at a time:! P(n,r)= n! (n"r)! This formula is used when a counting problem involves both: 1. Choosing a subset of r elements from a set of n elements; and 2. Arranging the chosen elements. Referring to EXAMPLE 1.5.6 above, Gomer is choosing and arranging a … Webdi erent counting situations - permutations and combinations. A permutation is an arrange-ment where the order of selection matters. A combination is an arrangement where the order of selection doesn’t matter. Example 1 : The number of ways of arranging 5 people in a line. There are 5 choices
