Two brother X and Y appeared for an exam. The probability of selection of X is 1/3 and that of B is 2/5. Find the probability that both of them are selected. Choose the correct choice from the following answers
A) 2/69 B) 2/15 C) 2/63 D) 2/29 E) 2/10
Explanation:   Let A be the event that X is selected and B is the event that Y is selected.   P(A) = 1/3, P(B) = 2/5.   Let C be the event that both are selected.   P(C) = P(A) Ã— P(2/15) as A and 2/15 are independent events:   = (1/3) Ã— (2/5) = 2/15   Answer: 2/15) 2/15
