There are 13 cards (A, K, Q, ..., 2), so choose one of them to be the 4 matching cards. There are 13C1 = 13 ways to do that.

Next, we need to pick the 5th card and there are 52 - 4 = 48 to pick from, So, there are 48C1 = 48 ways to pick the 5th card.

In total, the Numerator = 13 x 48 = 624

Now, the Denominator = 52C5 = 2,598,960

P = 624 / 2,598,960 = 1/4165

Hope that helps
