Answer 1

Answer:

120 ways

Step-by-step explanation:

This is a pretty straightforward question. We are asked how many ways can 5 printers be displayed on one shelf. We use the formula of factorial in getting the number of ways, i.e

n! = n * (n-1) * ..... 1, in the question given, our n = 5, so if we plug it in, we get

n! = 5 * (5-1) * (4-1) * (3-1) * (2-1) * 1

n! = 5 * 4 * 3 * 2 * 1

n! = 120.

Thus, there are 120 different ways to display the five types of laser printer on a shelf.
