a card is drawn from a pack of 52 cards . the probability of getting a queen of club or a king of heart is :
"here , n ( s ) = 52 . let e = event of getting a queen of club or a king of heart . then , n ( e ) = 2 . p ( e ) = n ( e ) / n ( s ) = 2 / 52 = 1 / 26 answer should be a"
divide(subtract(52, multiply(const_4, const_4)), 52)
