16. Suppose that E and F are two events and that P(E and F) = 0.2 and P(E) = 0.5. What is P(F | E)? 17. For the month of January in a certain city, 72% of the days are cloudy. Also, in the month of January in the same city, 35% of the days are cloudy and foggy. What is the probability that a randomly selected day in January will be foggy if it is cloudy? 18. Find the probability P(E or F) if E and F are mutually exclusive, P(E) = 0.30, and P(F) = 0.2
