A standard deck of 52 playing cards contains 13 cards in each of four suits: hearts, diamonds, clubs, and spades. Four cards are drawn from the deck at random.What is the approximate probability that exactly three of the cards are diamonds?

There are 13 diamonds and 39 non-diamonds. The probability of exactly three diamonds among four cards is (13 choose 3)(39 choose 1) divided by (52 choose 4), which is 11,154 ÷ 270,725 ≈ 0.041, or about 4%. So the correct choice is 4%.
