A standard 52 card deck was used. A queen was drawn first without replacement, leaving 51 cards. The probability of drawing an ace on the second draw given the first card was a queen is 4/51, as there were 4 aces remaining among the 51 cards.

2. Two cards are selected in a sequence from a standard deck of 52 playing cards. Find the probability that the second card is an ace, given that the first card was a queen. ( Assume that the queen is not replaced.) Then…

3. Because the first card is a queen and is not replaced, the remaining deck has 51 cards, 4 of which are aces because they were not previously drawn so… P ( Q / A) = 4/51= 0.078.
