The airline industry defines an on time flight as one that arrives within 15 minutes of its scheduled time. The ­following table shows the number of on time and late flights leaving Philadelphia and arriving in Orlando ­during a recent time period by airline:

a. What is the probability that a randomly selected flight was from Southwest and was on time?

b. What is the probability that a randomly selected flight was from Air Tran or was on time?

c. Given that the flight was late, what is the probability that it was from US Airways?

d. Given that the flight was from Southwest, what is the probability that it was late?

e. Construct a decision tree for these probabilities.
