A deck of 52 cards is shuffled and then divided into two piles of 13 cards and 39 cards. A card is drawn from the 13 card pile and it turns out to be an ace. The ace is then placed in the 39 card pile. The second pile (now containing 40 cards) is then shuffled and a card is drawn from it. Compute the probability that this drawn card is an ace. Please note that there are a total of 4 aces in a standard deck of 52 cards.
