a ticket from indianapolis to orlando on deleast airlines sells for $150. the plane can hold 100 people. it costs deleast $8000 to fly an empty plane. each person on the plane incurs variable costs of $30 (for food and fuel). if the flight is overbooked, anyone who cannot get a seat receives $300 in compensation. on average, 95% of all people who have a reservation show up for the flight. to maximize expected profit, how many reservations for the flight should deleast book? (hint: the function riskbinomial can be used to simulate the number who show up. it takes two arguments: the number of reservations booked and the probability that any ticketed person shows up.)
