Explanation:
This is more properly a Statistics question than a Calculus one.
It is a "Combination" with 3 items in 4 locations, where the order is NOT important (you just want four pieces) and duplication is allowed (you might end up with all four of one item). The relevant formula is:
where n is the number of things to choose from, and we choose r of them (No repetition, order doesn't matter). The "!" means "factorial", or the digits of the number multiplied by each other.

IN this case, n = 3 and r = 4.
