What is the probability that a number selected from numbers 1,2,3,...,30, is prime number, when each of the given numbers is equally likely to be selected?  Select.
A) 1011	B) 1041	C) 9018	D) 1030	E) 1020
X={2,3,5,7,11,13,17,19,23,29}X={2,3,5,7,11,13,17,19,23,29}   n(X)=10,n(S)=30   Hence required probability,   =n(X)n(S)   =1030   1030
