Pick B.

We need one from each deck, and then the remaining two can be any two of the remaining 48 cards.
i.e: 13C1*13C1*13C1*13C1*48C2 = 13^4*24*47

Can you please explain why it is not 13^4*48*47

Thanks

If you do 48*47, you are saying that the order in which you pick the cards matter. This is a combination problem because you just have to pick any two cards, the order in which they appear does not matter.
