A and B are two events.

Let P (A) = 0.6, P (B) = 0.5 and P (A and B) = 0.2.

Which statement is true?

A. A and B are not independent events because P (A|B) ≠P (A)

B. A and B are independent events because P (A|B) = P (A) and P (B|A) = P (B)

C. A and B are independent events because P (B|A) ≠P (B) and P (A|B) ≠P (A)

D. A and B are not independent events because P (A|B) = P (A) and P (B|A) = P (B)
