A and B are two events. Let P(A) = 0.65, P (B) = 0.17, P(A|B) = 0.65 and P(B|4) = 0.17 Which statement is true?

1. A and B are not independent because P(A|B) + P(A) and P(B|4) + P(B).

2. A and B are not independent because P (A|B) + P(B) and P(B|4) + P(A)

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

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