Two brothers Ram and Ravi appeared for an exam. The probability of selection of Ram is 4/7 and that of Ravi is 1/5. Find the probability that both of them are selected.
Choose the correct choice from the following:  A) 4/35  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) = 4/7   P(B) = 1/5   Let C be the event that both are selected.   P(C) = P(4/35) x P(B) as 4/35 and B are independent events:   = 4/7 x 1/5 = 4/35   4/35NSWER:4/35
