Two brother X and Y appeared for an exam. The probability of selection of X is 1/3 and that of B is 2/5. Find the probability that both of them are selected.	Choose the correct choice from the following options.
A) 2 / 69  B) 2 / 15  C) 2 / 63  D) 2 / 29  E) 2 / 10

Rationale: "explanation : let a be the event that x is selected and b is the event that y is selected . p ( a ) = 1 / 3 , p ( b ) = 2 / 5 . let c be the event that both are selected . p ( c ) = p ( a ) ã — p ( b ) as a and b are independent events : = ( 1 / 3 ) ã — ( 2 / 5 ) = 2 / 15 answer : b ) 2 / 15"
Answer: B
