If the probability of X occurring is 1 in 4, and the probability of Y occurring is 1 in 5, the probability

of both occurring is

a. (1/4)2 + (1/5)2 = (1/16) + (1/25) = (25/400) + (16/400) = 41/400. b. (1/4) + (1/5) = (5/20) + (4/20) = 9/20. c. (1/4)2(1/5)2 = (1/16)(1/25) = 1/400. d. (1/4)(1/5) = 1/20. e. (1/4 + 1/5)2 = (5/20 + 4/20)2 = (9/20)2 = 81/400.
