two cards are drawn together from a pack of 52 cards the probability that one is the spade and one is a heart is ?
"let s be the sample space then n ( s ) = 52 c 2 = ( 52 * 51 ) / ( 2 * 1 ) = 1326 let e be the event of getting 1 spade kings and 1 heart let n ( e ) = number of ways of chossing 1 spade out of 13 and 1 heart out of 13 = ( 13 c 1 * 13 c 1 ) = 13 * 13 = 169 p ( e ) = n ( e ) / n ( s ) = 169 / 1326 = 13 / 102 answer ( d )"
multiply(divide(multiply(divide(52, const_4), divide(52, const_4)), multiply(52, 52)), const_2)
