Question

Five students are in line for the bathroom. How many different ways can they be lined up.

Answer 1

To get the number of different ways for the students to line up, we are going to find the factorial of the number of students as seen below:

`\begin{gathered} 5!=5*4*3*2*1 \\ =120 \end{gathered}`

Hence, the 5 students can be lined up in 120 different ways.
