P(Jane and John) = P(John | Jane) * P(Jane) = (0.7) * (0.5) = 0.35

B

P(Jane | John) = P(Jane and John) / P(John) = (0.35) / (0.4) = 0.875

C

P(Jane) * P(John) = (0.5) * (0.4) = 0.20

P(Jane and John) ≠ P(Jane) * P(John) = 0.35 ≠ 0.20

The two events are not independent do to the fact that P(Jane and John) ≠ P(Jane) X P(John). With that being said, John and Jane do not watch the show independently of each other.
