Multiple Choice

Events X and Y are independent of each other. If the probability of event X occurring is 1 in 4, and the probability of event Y occurring is 1 in 5, the probability of both events 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
