find the probability that a number selected from numbers 1 , 2 , 3 , . . . , 35 is a prime number , when each of the given numbers is equally likely to be selected ?
"let x be the event of selecting a prime number . x = { 2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 , 29 , 31 } n ( x ) = 11 , n ( s ) = 35 hence , the required probability is 11 / 35 . answer : b"
divide(multiply(3, const_5), 35)
