The probability that a flight that departs on schedule also arrives on schedule can be found using the formula for conditional probability:
P(arrives on schedule | departs on schedule) = P(arrives on schedule and departs on schedule) / P(departs on schedule)
P(arrives on schedule | departs on schedule) = 0.69 / 0.81 = 0.85
Therefore, the probability that a flight that departs on schedule also arrives on schedule is 0.85. Rounded to two decimal places, the answer is 0.85.
