Two brothers Ram and Ravi appeared for an exam. The probability of selection of Ram is 5/7 and that of Ravi is 1/5. Find the probability that both of them are selected.
Choose the correct choice.
A) 2/35	B) 2/3	C) 7/35	D) 1/7	E) 7/5
Let A be the event that Ram is selected and B is the event that Ravi is selected.   P(A) = 5/7   P(B) = 1/5   Let C be the event that both are selected.   P(C) = P(A) x P(B) as A and B are independent events:   = 5/7 x 1/5 = 1/7   ANSWER:1/7
