- What is the probability that a number selected from numbers 1,2,3,.
Question 1:
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 ? A. 9/30
B. 8/30
C. 10/30
Feedback 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
n(X)= 10, n(S)=30
Hence required probability = n(X)/n(S)= 10/30
D. 11/30
