Chapter 11.6, Problem 2E

To determine

To calculate: thelisting all the permutations of the letters A, B, C, and D.

Answer to Problem 2E

The list of permutations of the letters A, B, C, and D is A , B , C , D

AB, AC, AD, BC, BC, CD

ABC, ACD, ABD, BCD

ABCD

Explanation of Solution

Given : the lettersare A, B, C, Dprovided in the question,

Calculation : tolist the permutations of the letters A, B, C, and D ,

Permutations to select only letter : A , B , C , D

Permutations to select two letters : AB, AC, AD, BC, BC, CD

Permutations to select three letters: ABC, ACD, ABD, BCD

Permutations to select four letters: ABCD

Hence,The list of permutations of the letters is A , B , C , D

AB, AC, AD, BC, BC, CD

ABC, ACD, ABD, BCD

ABCD
