For two events, P(A)=0.4, P(B)=0.3, and P(A∩B)=0.12. Which of the following is true?

A. A and B are complementary.

B. A and B are independent.

C. A and B are mutually exclusive.

D. P(A∪B)=0.52.

Answer: Option B

Solution (By JKSSB Mock Tests)

0.4×0.3=0.12, so independent. Mutually exclusive would need 0. P(A∪B)=0.4+0.3-0.12=0.58.
