WebbSolved Examples Using Permutation Formula Question 1: Find the number of permutations if n = 9 and r = 2. Solution: Given n = 9 and r = 2. Permutation = n P r = n!/ (n−r)! = 9! / (9-2)! = 9! /7! = 72 Thus, the number of permutations = 72 Question 2: Find how many ways you can rearrange letters of the word “BANANA” all at a time. Solution: WebbRelated Probability Calculator ... There are different types of permutations and combinations, but the calculator above only considers the case without replacement, ... the equation for calculating permutations removes the rest of the elements, 9 × 8 × 7 × ... × 2 × 1, or 9!.
