Consider the decision a contractor faces when bidding on a construction job. The contractor must first decide on the bid amount, then after submitting the bid, waits to see if he won the contract. After winning the contract, he faces additional uncertainties with regards to materials cost, labor costs, delays, etc. Each of these uncertainties influence the final profit, and a summary of this decision is given in Figure 4.46. Build and solve the tree in Figure 4.46 using Precision-Tree. Use this problem to discuss why the most likely value (the mode) is different from the expected value. What conclusions can be drawn based on the mode, and how does this differ from the conclusions based on the expected value?
