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 .
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
multiply(divide(const_1, reminder(17, const_10)), divide(const_2, reminder(29, const_10)))
