Overbooking of passengers on intercontinental flights is a common practice among airlines. Aircraft which are capable of carrying 340 passengers are booked to carry 365 passengers. If on average 10 % passengers who have booked fail to turn up for their flights, wat is the average probability that at least one passenger who has a booking will end up without a seat on a particular flight? [Hint: apply the normal approximation to the binomial distribution]
