Answer:

P(F | E)  = 0.75

Step-by-step explanation:

It is given that P(E [tex]\cap[/tex] F) = 0.3

It is also given that P(E) = 0.4

P(F | E)  = [tex]\frac{P(E \cap F)}{P(E)} = \frac{0.3}{0.4} = 0.75[/tex]

Therefore P(F | E)  = 0.75

This is the conditional probability that the event F occurs given that event E has occurred.

This conditional probability is found by dividing the probability of events E and F occurring by the probability of event E occurring.
