You have a standard deck of 52 cards. How many possibilities are there if your turn 6 cards over one by one in the order: an ace, a king, an Ace, a King, an Ace, and a King?

I am trying to help my friend out with his homework but its been so long since I have messed with permutations, combinations, and probability that I am blanking on remembering how to do it. Any help would be greatly appreciate for us. Thanks.
