Question

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 points.

Answer 1

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%.
