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: Given word: BANANA

WebSep 6, 2015 · 1) forming a permutation of P E P P E R, which can be done in, say, x ways; 2) assigning subscripts to the P's, which can be done in 3! ways; and then 3) assigning subscripts to the E's, which can be done in 2! ways. Therefore 6! = x ( 3!) ( 2!), so x = 6! 3! 2! Here is an alternate way to do this: ipledge still down
