If the pack has 52 cards then:
in a pack of 52 cards there are total 26 black cards.
Probability that one card is black is 26 / 52 = 1 / 2
Probability that both cards are black is = 1 / 2 ∙ 1 / 2 = 1 / 4
in a pack of 52 cards there are total 26 black cards.
Probability that one card is black is 26 / 52 = 1 / 2
Probability that both cards are black is = 1 / 2 ∙ 1 / 2 = 1 / 4

is 26/52 or 1/2. Since the first card is returned to the pack, the probability of getting a black card on the second draw is still 1/2. Therefore, the probability of getting two black cards in a row is 1/2 x 1/2 = 1/4 or 0.25 or 25%.
