# Probability Distribution and the Rxpected PW

Problem 18.31 (Subject: Uncertainty & Probability)

Use an economic decision tree to find the probability distribution and the expected PW for an assembly line modification. The first cost is 80K, and its salvage value is $0. The firm's interest rate is 9%. The savings shown below depend on whether the assembly line runs one, two, or three shifts and on whether the product is made for 3 or 5 years.

Savings/Year Probabilities Useful Life(Years) Probability
