(Answered) Question no-shows an airline offers discounted

Statistics

Question: No-shows. An airline offers discounted advancepurchase fares to customers who buy tickets more than 30 days before travel and charges regular fares for tickets purchased during those last 30 days.

The no-show rate among people who paid regular fares is 30%, but only 5% of customers with advance-purchase tickets are no-shows.

a) What percent of all ticket holders are no-shows?

b) What's the probability that a customer who didn't show had an advance-purchase ticket?

c) Is being a no-show independent of the type of ticket a passenger holds? Explain.
