Answer:
The probability of drawing a black card from a deck of 52 cards is 26/52 or 1/2, since there are 26 black cards in the deck.
The probability of drawing an Ace from a deck of 52 cards is 4/52 or 1/13, since there are 4 Aces in the deck.
Since the first card is replaced before drawing the second card, the outcome of the first card does not affect the probability of drawing an Ace on the second draw. Therefore, we can multiply the probabilities of the two events to find the probability of both events happening:
Probability of drawing a black card on the first draw = 1/2
Probability of drawing an Ace on the second draw = 1/13
Probability of both events happening = (1/2) x (1/13) = 1/26
Therefore, the probability that the first card is black and the second card is an Ace is 1/26.
