Two brother X and Y appeared for an exam. The probability of selection of X is 1/7 and that of B is 2/9. Find the probability that both of them are selected.  Choose the correct option:
A) 2/69  B) 2/60  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) = 1/7, P(B) = 2/9.   Let C be the event that both are selected.   P(2/63) = P(A) × P(B) as A and B are independent events:   = (1/7) × (2/9) = 2/63   Answer: 2/63) 2/63
