We have:
Total number of cards in a pack = 52
Total number of aces in a pack = 4
The probability of drawing an ace is:
[tex]P(one\text{ }ace)=\frac{4}{52}[/tex]The probability that both are aces is:
[tex]P(both\text{ aces\rparen=}\frac{4}{52}\cdot\frac{3}{51}=\frac{4\cdot3}{52\cdot51}=\frac{12}{2652}=\frac{1}{221}[/tex]Answer: the probability is 1/221
