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.
