Tik Ed McMаster is selling tickets tо а bаllооn ride. The ride takes place at dawn on Sunday because the winds are most calm at that time of day. Demand for the ride is equally likely to be 1, 2, 3, 4, or 5 units. Tik buys the tickets for $10 each and resells them for $20 each. Unsold tickets have no value, and he can only place one order for this week. If Tik has to place his order before knowing demand, how many should he order?
