The probability that only one project will complete on time is calculated by adding the probability that A completes on time and B does not with the probability that B completes on time and A does not. This is (0.85 * (1 - 0.65)) + (0.65 * (1 - 0.85)) = 0.2975 + 0.0975 = 0.395. Rounded to two decimal places, the closest option is 0.36.
