How many different ways can 9 trumpet players in the marching band line up?

362880 ways

Step-by-step explanation:

In this case, the order does matter therefore to know how many ways it can be aligned, we must resort to permutations.

The formula for permutations is:

P = n!

we know that there are 9 trumpet players, therefore:

P = 9!

P = 362880

So there are 362,880 ways to line up
