Question

Ms. White has 15 students in her first grade class. Troy is the line leader for the week, and Mackenzie is last because she was the line leader last week. In how many different ways can Ms. White's class line up for lunch this week?

Answer 1

13!
15!
15! ÷ 2!

Answer 2

As we have the first and last values as the fixed values, we can only per mutate the 13 left. So that'd make 13!

Answer 3

ok thanks
