Question

By rewriting the formula for the multiplication rule, you can write a formula for finding conditional probabilities. The conditional probability of event B occurring, given that event A has occurred, is P(B | A) = P(A and B)/P(A). Use the information below to find the probability that a fight 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 fight arrives on time is 0.86. The probability that a flight departs and arrives on time is 0.81. The probability that a fight departed on time given that it arrives on time is (Round to the nearest thousandth as needed.)

Explanation / Answer

here probabilty depart on time =P(A)=0.91

probabilty arrive on time P(B)=0.86

probabilty depart on time given arrive on time =P(A|B)=P(AnB)/P(B)=0.81/0.86=0.942
