A standard deck of 52 playing cards contains 13 cards in each of four suits: diamonds, hearts, clubs, and spades. Two cards are chosen from the deck at random.What is the approximate probability of choosing one club and one heart?

There are 13 clubs and 13 hearts, so there are 13 × 13 = 169 ways to choose one of each. The total number of two-card choices is 52 × 51 ÷ 2 = 1,326. Thus the probability is 169 ÷ 1,326 ≈ 0.1275, which is choice D, 0.1275.
