Two brother X and Y appeared for an exam. The probability of selection of X is 1/5 and that of B is 2/7. Find the probability that both of them are selected. Choose the correct choice:
A) 2/35
B) 2/30
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) = 1/5, P(B) = 2/7.   Let C be the event that both are selected.   P(C) = P(2/35) Ã— P(B) as 2/35 and B are independent events:   = (1/5) Ã— (2/7) = 2/35   2/35nswer: 2/35) 2/35
