Everett Ltd is a company who sells CNC machines to universities for educational purposes. The company observes the number of CNC machines on its hand (call it i) at the beginning of a month. If at the beginning of a month i ≤ 1, then the company orders 3 - i machines (so, the number of inventories is completed to 3). If i ≥ 2, then 0 machines are ordered. It is known that delivery of all ordered machines is immediate. The customers are equally likely to demand 0, 1, 2, or 3 machines from Everett Ltd. during the month.
