A card is chosen from a pack of playing cards then returned to the pack.A second card is chosen.What is the probability that both cards are black

Answer 1

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

Answer 2

1/2
52/2 =26
2/26=1/2 so answer is 1/2 or 50%
Probability getting a black cards

Answer 3

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%.
