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? Pick one
A) 10/30
B) 20/30
C) 1
D) 5/30
E) 15/30
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 10/30 is answer
