Q: You are given an answer. Create a question for the answer.
Hence there are 2 choices for the fourth digit and only 1 choice for the fifth digit. Thus you have made 5 4 3 2 1 = 120 choices and there are 120 possible 5 digit numbers made from 1, 2, 3, 4 and 5 if you don't allow any digit to be repeated. Now consider the possibilities with 13 as the first two digits.
A:
1 2 3 4 5 how many combinations?
