1 answer:

5 0

To find the probability that they are both aces, you will find the probability of them being aces in both cases and then multiply these together.

There are 4 aces in a deck of cards.

4 4
52 x 52

You can factor out 4's all the way around to get
1 1 1
13 x 13 = 169

The probability is 1/169 change of both being aces.
