Find the probability that a number selected from numbers 1, 2, 3,..., 30 is a prime number, when each of the given numbers is equally likely to be selected?	Select.
A) 10/30 B) 1/30 C) 8/30 D) 3/30 E) 7/30
Let X be the event of selecting a prime number.   X = {2, 3, 5, 7, 11, 13, 17, 19, 23,29}   n(X) = 10,   n(S) = 30   Hence, the required probability is 10/30.   ANSWER:8/30
