The probability that the first card drawn is an ace is $\frac{4}{52}$, since there are four aces in the deck. The probability that the second card drawn is an ace is $\frac{3}{52}$, since there are 3 aces left but there are still 52 cards. Hence, the probability both cards drawn are aces is $\frac{4}{52} \cdot \frac{3}{52}$.
