- By rewnting the formula for the multiplication rule, you can write a formula for finding P(A and B) P(A) conditional probabilities. The conditional probability of event B occurring, given that event A has occurred, is P(B 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 0.91. The probability that a flight arrives on time is 0.89. The probability that a flight departs and arrives on time is 0.82. The probability that a flight departed on time given that it arrives on time is. (Round to the nearest thousandth as needed.) esYou're on our way to earn a degree.
