Use the multiplication principle to tell the total number of three-card hands (permutations) that can be made with two aces

We are asked for the total or three card hands that can be made with two aces. The three-card hand should have two aces. We will use permutation in solving this problem and the solution is shown below:

nPr = n! / (n-r) !

n=3

r=2

3P2 = 3! / (3-2) !

3P2 = 6

The answer is 6.
