Do we assume that P(F) can be equal to zero? How?

P(F) can never be 0

P(E and F) = P(E) x P(F) = 0.42

P(E) = 0.42/ P(F) and the denominator can never be 0

The minimum value of P(E) would be = 0.42 / 1 = 0.42, which is < 0.58

But P(F} can also be 0.5 for instance, and in that case:

P(E) = 042/0.5 = 0.84, which is >0.58

Thus, D
