Mark the correct alternative in each of the following:

A and B are two events such that P(A) = 0.25 and P(B) = 0.50. The probability of both happening together is 0.14. The probability of both A and B not happening is

A. 0.39

B. 0.25

C. 0.11

D. none of these

Answer :

Given P(AB)=0.14,P(A)=0.25,P(B)=0.50

By addition theorem,



P(both A and B not happening)=1-P(AB)=1-0.61=0.39
