Question

Two events 'A' and 'B' are said to be independent if

विकल्प

• A and B are mutually exclusive

• P(A' B') = [1 – P(A)][1 – P(A)][1 – P(B)]

• P(A) = P(B)

• P(A) + P(B) = 1

Answer 1

P(A' B') = [1 – P(A)][1 – P(A)][1 – P(B)]

Explanation:

Two events are. independent

If P(A ∩ B) = P(A) × P(B)

or P(A¹ ∩ B) = P(A¹) P(B¹) = [1 – P(A)] [1 – P(B)]
