By rewriting the formula for the multiplication​ rule, you can write a formula for findingconditional probabilities. The conditional probability of event B​ occurring, given that event A has​ occurred, isUpper P left parenthesis Upper B vertical line Upper A right parenthesis equals StartFraction Upper P left parenthesis Upper A and Upper B right parenthesis Over Upper P left parenthesis Upper A right parenthesis EndFractionP(B A)=P(A and B)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 is0.91.The probability that a flight arrives on time is0.86.The probability that a flight departs and arrives on time is0.84.

Answer:

Explanation:

Let A be the event that Flight departs on time

B be the event that Flight arrive on time

Probability that an airplane flight departs on time
P(A)= 0.91

Probability that Flight arrives on time
P(B)=0.86

Probability that Flight departs and arrives on time
P\left ( A\cap B\right )=0.84

Probability that a flight departed on time given that it arrives on time
=(P\left ( A\cap B\right ))/(P\left ( B\right ))


=(0.84)/(0.86)=0.97
