Please help solve the problem:

By rewriting the formula for the multiplicationrule, you can write a formula for finding

conditional probabilities. The conditional probability of event Boccurring, given that event A hasoccurred, is P(BA)=P(AandB)P(A). Use the information below to find the probability that a flight departed on time given that it arrives on time.

The probability that an airplane flight departs on time is 0.89.

The probability that a flight arrives on time is 0.86.

The probability that a flight departs and arrives on time is 0.81.

The probability that a flight departed on time given that it arrives on time is
