An airline, believing that 5% of passengers fail to show for flights, overbooks (sells more tickets than there are seats). suppose that for a particular flight involving a jumbo-jet with 267 seats, the airline sells 278 tickets.

question 1. what is the expected number of ticket holders that will fail to show for the flight? (use 2 decimal place in your answer.)

question 2. what is the probability that the airline will not have enough seats for all the ticket holders who show for the flight?
