Two brother X and Y appeared for an exam. The probability of selection of X is 1/5 and that of B is 2/3. Find the probability that both of them are selected.  Choose one:
A) 2/69	B) 2/20	C) 2/18	D) 2/29	E) 2/15
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) = 2/3.   Let C be the event that both are selected.   P(C) = P(A) Ã— P(B) as A and B are independent events:   = (1/5) Ã— (2/3) = 2/15   Answer: 2/15) 2/15
