Answer 2

Step-by-step explanation:

Given Find the number of distinguishable permutation of the digits of the number 911 912 271

• So we need to find the distinguishable permutations of the digits of the number 911912271
• Let k be the number of distinguishable permutations and the given number is 911912271.
• In this we have the numbers
•    there are two 9’s, one 4, two 2’s and one seven. So we get
•                   k = n! / p! q! r!
•                      = 9! / 2! 4! 2! 1!
•                      = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 / 2 x 4 x 3 x 2 x 2
•                      = 9 x 7 x 5 x 4 x 3 x 1
•                       = 3780
