Question #3
Assertion (A): If A and B are independent events, then A' and B' are also independent. Reason (R): P(A'∩B') = P(A')P(B') when A and B are independent. Choose the correct option:
A. Both A and R are true, but R is not the correct explanation of A
B. A is false, R is true
C. A is true, R is false
D. Both A and R are true, and R is the correct explanation of A
