Two brother X and Y appeared for an exam. Let A be the event that X is selected and B is the event that Y
is selected.
The probability of A
is 17 and that of B is 29. Find the probability that both of them are selected.	Choose the correct option.
A) 2 / 63 B) 2 / 67 C) 2 D) 3 / 31 E) 4

Rationale: given , a be the event that x is selected and b is the event that y is selected . p ( a ) = 17 , p ( b ) = 29 . let c be the event that both are selected . p ( c ) = p ( a ) × p ( b ) as a and b are independent events : = ( 17 ) × ( 29 ) = 2 / 63 answer is a
Answer: A
