orders

1 answer

There are 24 different orders in which Mrs. Thompson can line up the markers.

To see why, we can use the permutation formula:

n! / (n - r)!

where n is the total number of items, and r is the number of items being selected and ordered.

In this case, we have 4 markers and we want to line them up in a specific order, so r = 4.

Plugging in the numbers:

4! / (4 - 4)! = 4! / 0! = 24

So there are 24 different orders in which Mrs. Thompson can line up the markers.
