I have most of this answered. I am having difficulty in answering #3 & #4. How do I determine the expected value in #4 and the expected profit in #3?

Thanks!

BUYU Manufacturing has beencontracted to provide SAEL Electronics with printed circuit and motherboards (PC) boards under the following terms:

• 100,000 PC boards will be delivered to SAEL in one month.
• In3 months, SAEL has an option to take the delivery of an additional 100,000 boards by giving BUYUa 30-day notice.
• SAEL will pay $5 for each board it takes.

BUYU manufactures the PC boards through a process called batching, and manufacturing costs are as follows:

• The manufacturing batch run has a fixed setup cost of $250,000, regardless of the run size.
• The marginal manufacturing cost is $2.00 per board, regardless of the size of the batch run.

BUYU must decide whetherit should manufacture all 200,000 PC boards now, or ifit should manufacture 100,000 now and the other 100,000 boards only if SAEL decides to buy them. If BUYU manufactures 200,000 now and SAEL does not exercise its option, then BUYU will lose the manufacturing cost of the extra 100,000 boards. BUYU believes that there is a 50% chance thatSAEL will exercise its option to buy the additional 100,000 PC boards.

1. Discuss the potential profit of manufacturing all 200,000 boards now.
2. Draw a decision tree for the decision that BUYU faces.
3. If BUYU uses its expected profit as the basis for its decision, determine the preferred course of action.
4. Determine the range of values of the probability that SAEL will exercise its option, making the decision found in part c as optimal, and determine the expected value of perfect information about whether SAEL will exercise its option.
