Question

Question;Christina started a business of rehabbing old homes. He recently purchased a circa-1800 Victorianmansion and converted it into a three-family residence. Recently, one of his tenants complained that therefrigerator was not working properly. As Christina?s cash flow was not extensive, he was not excitedabout purchasing a new refrigerator. He is considering two other options: purchase a used refrigerator orrepair the current unit. He can purchase a new one for \$400, and it will easily last three years. If he repairsthe current one, he estimates a repair cost of \$150, but he also believes that there is only a 30 percentchance that it will last a full three years. If the repaired refrigerator does not last three years, he will haveto buy a new one (\$400). If he buys a used refrigerator for \$200, he estimates that there is a 60%probability that it will last at least three years. If it breaks down, he will still have the option of repairing itfor \$150 or buying a new one. If he repairs, there is a 30 percent change that it will last. If it doesn?t hewill have to buy a new one.a. (5 points) Construct a decision tree for this problem.b. (5 points) Identify the strategy that minimizes Christina?s expected cost for the next threeyears.
