A rm that plans to expand its product line must decide whether to build a small or a large facility to produce the new
products. If it builds a small facility and demand is low, the net present value after deducting for building costs will be
$400,000. If demand is high, the rm can either maintain the small facility or expand it. Expansion would have a net
present value of $450,000, and maintaining the small facility would have a net present value of $50,000.
If a large facility is built and demand is high, the estimated net present value is $800,000. If demand turns out to be low,
the net present value will be -$10,000.
The probability that demand will be high is estimated to be .60, and the probability of low demand is estimated to be .40.

a. Analyze using a tree diagram.
b. Compute the EVPI. How could this information be used?
c. Determine the range over which each alternative would be best in terms of the value of P(demand low).
