四、考量一總體經濟模型：

IS 曲線為 y=120-250r (y 為實質產出，r 為實質利率)；

LM 曲線為 $\frac{M}{P}$=0.5y-250r (M 為貨幣供給量，P 為物價)，M=300；

總體生產函數為 y=20√N (N 為勞動雇用量)；

勞資雙方議定名目工資(W)為 20，且資方有權決定勞動雇用量。

3. An airplane has 15 seats and 15 passengers, each with an assigned seat (passenger $ k $ assigned to seat $ k $). Passenger No.1 boards first but has lost the boarding pass and chooses a seat uniformly at random. Passengers No.2 through No.14 board in order: each takes their assigned seat if available; otherwise, they choose a remaining seat uniformly at random. Passenger No.15 boards last. What is the exact probability that Passenger No.15 sits in the assigned seat (seat No.15)? (10%)(Note: You are asked to answer in percentages, counted to two decimal places.)
