How many ways can 5 students line up?

Answer 1

To do this you would use a ! function in your calculator. In short this takes any number and multiplies it by all the number beneath it. In this case it would say 5 x 4 x 3 x 2 x 1. You arrange it this way because they're are five different people in spot on, but once spot one is taken there are only 4 people left for spot two and so on. So, the answer to this would be 120 different combinations.

The reasoning is the following: To select the first student, you have 5 options. For the second, whichever you chose for the first student, you have 4 options... etc.

Answer 2

120 ways by 5! = 120
