Answer 2

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%.
