Probability question.

Two cards are drawn from a well-shuffled deck of 52 cards.

Find the probability they are both aces if the first card is replaced.


All help is very much appreciated :)

Respuesta :

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.
