Extracted text: A construction consultancy firm calculates the probability that a dam project starts on time is P(S) = 0.83; the probability that it finishes on time is P(F) = 0.82; and the probability that it starts and finishes on time is P(S n F) = 0.78. Find the probability that the project a) finishes on time, given that it started on time. b) finishes on time, given that it did not start on time.
