An airline has 81% of its flights depart on schedule. it has 69% of its flights depart and arrive on schedule. find the probability that a flight that departs on schedule also arrives on schedule. round the answer to two decimal places.

Given:

81% flight departs on schedule

69% flight departs and arrive on schedule

Probability that a flight that departs on schedule also arrives on schedule.

Probability that flight departs on schedule * Probability that flight arrives on schedule = Probability that flight departs and arrives on schedule

0.81 * x = 0.69

x = 0.69 / 0.81

x = 0.8519 or 85.19%

The probability that a flight that departs on schedule also arrives on schedule is 85.19%.
