Suppose the probability of X occurring is 1 in 4, and the probability of Y occurring is 1 in 5. What is the probability of both occurring?
A) (1/4) + (1/5) = (5/20) + (4/20) = 9/20
B) (1/4) 2 + (1/5) 2 = (1/16) + (1/25) = (25/400) + (16/400) = 41/400
C) (1/4) × (1/5) = 1/20
D) (1/4) 2 × (1/5) 2 = (1/16) × (1/25) = 1/400
