If A and B are independent events, which equation must be true?

Question

A. 

P(B|A) = P(A)

B. 

P(B|A) = P(B)

C. 

P(B|A) = P(A) × P(B)

D. 

P(B|A) = P(A) + P(B)

Answer 1

Two events A and B are independent if P(A|B) = P(A) and P(B|A) = P(B)

The correct answer is B : P(B|A) = P(B)

Hope this helps
