what is the probability that a number selected from number 1 to 30 is prime number , when each of the given numbers is equally likely to be selected ?
x = { 2,3 , 5,7 , 11,13 , 17,19 , 23,29 } n ( x ) = 10 n ( s ) = 30 hence required probability = n ( x ) / n ( s ) = 10 / 30 option a is answer
divide(multiply(const_5, const_2), 30)
