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