four dice are thrown simultaneously . find the probability that all of them show the same face .
"total no of elementary events = 6 ^ 4 n ( s ) = 6 ^ 4 x = { ( 1,1 , 1,1 ) ( 2,2 , 2,2 ) . . . . . ( 6,6 , 6,6 ) } n ( x ) = 6 n ( x ) / n ( s ) = 6 / 6 ^ 4 = 1 / 216 answer a"
multiply(divide(const_3, add(const_3, const_3)), divide(const_3, add(const_3, const_3)))
