Question

a card is drawn at random from a standard deck. that card is not put back in the deck, and a second card is drawn at random from the remaining cards in the deck. what is the probability that both of the cards are nines? do not round your intermediate computations. round your final answer to four decimal places.

Answer 1

Chance that the first card is a 9: 4/52 or 1/13

Chance that the second card is a 9: 3/52

Total probability is 1/13 • 3/52 ≈ 0.00443786982249

0.004438 or 0.4438%
