- Swell Productions is sponsoring an outdoor conclave for owners of collectible and classic Fords. The concession stand in the T-Bird area will sell clothing such as T-shirts and official Thunderbird racing jerseys. Jerseys are purchased from Columbia Products for $40 each and are sold during the event for $75 each. If any jerseys are left over, they can be returned to Columbia for a refund of $30 each. Jersey sales depend on the weather, attendance, and other variables. The following table shows the probability of various sales quantities. How many jerseys should Swell Productions order from Columbia for this one-time event?Sales Quantity Probability Quantity Sales Probability100 0.05 400 0.34200 0.11 500 0.11300 0.34 600 0.05arrow_forwardHarley, an ice-cream vendor, purchases each pint of ice-cream for $7 and sells for $20 each. At the end of the week, the unsold ice-cream can be salvaged for $2 each. From past experience, Harley has estimated the sales probabilities as below. What is the optimal number of pints Harley should purchase? Number of Ice-creams Sold, Probability 1 = 0.05, 2 = 0.1, 3 = 0.2 , 4 = 0.25, 5 = 0.15, 6 = 0.1, 7 = 0.08, 8 = 0.07arrow_forwardEllie Daniels has $200,000 and is considering three mutual funds for investment—a global fund, an index fund, and an Internet stock fund. During the first year of investment, Ellie estimates that there is a .70 probability that the market will go up and a .30 probability that the market will go down. Following are the returns on her $200,000 investment at the end of the year under each market condition: Market Conditions Fund Up Down Global $25,000 $ -8,000 Index 35,000 5,000 Internet 60,000 -35,000 At the end of the first year, Ellie will either reinvest the entire amount plus the return or sell and take the profit or loss. If she reinvests, she estimates that there is a .60 probability the market will go up and a .40 probability the market will go down. If Ellie reinvests in the global fund after it has gone up, her return on her initial $200,000 investment plus her $25,000 return after 1 year will be $45,000. If the market goes down, her loss will be $15,000. If she reinvests after…arrow_forward
- Johnson Chemicals is considering two options for its supplier portfolio. Option 1 uses two local suppliers. Each has a “unique-event” risk of 5%, and the probability of a “superevent” that would disable both at the same time is estimated to be 1.5%. Option 2 uses two suppliers located in different countries. Each has a “unique-event” risk of 13%, and the probability of a“super-event” that would disable both at the same time is estimatedto be 0.2%. a) What is the probability that both suppliers will be disruptedusing option 1?b) What is the probability that both suppliers will be disruptedusing option 2?c) Which option would provide the lowest risk of a total shutdown?arrow_forwardFollowing is the payoff table for the Pittsburgh Development Corporation (PDC) Condominium Project. Amounts are in millions of dollars. State of Nature Decision Alternative Strong Demand S1 Weak Demand S2 Small complex, d1 8 7 Medium complex, d2 14 5 Large complex, d3 20 -9 Suppose PDC is optimistic about the potential for the luxury high-rise condominium complex and that this optimism leads to an initial subjective probability assessment of 0.8 that demand will be strong (S1) and a corresponding probability of 0.2 that demand will be weak (S2). Assume the decision alternative to build the large condominium complex was found to be optimal using the expected value approach. Also, a sensitivity analysis was conducted for the payoffs associated with this decision alternative. It was found that the large complex remained optimal as long as the payoff for the strong demand was greater than or equal to $17.5 million and as long as the payoff for…arrow_forwardA property development company is planning to build a block of student apartments in Lusaka’s Mass Media area. The company is yet to decide what size of block to build: a small, medium, or large. The payoffs of each size will depend on the demand for student accommodation in the area, which could be low, medium, high. The Developer estimates a 25%, 35%, and 40% chance of low, medium, and high demand, respectively. Below is a payoffs matrix (in K’000) showing the annual payoffs for the decision problem. Size of Block Market Demand Low Medium High Small 400 400 400 Medium 200 500 500 Large -400 300 800 Required: Identify the decision alternatives and uncertain conditions surrounding them? What is the optimal decision if the Developer is conservative? What is the optimal decision if the Developer is a risk taker? What is the optimal decision if the Developer wishes to minimize the Expected Opportunity Loss on the decision to be taken?arrow_forward
- Cheryl Druehl Retailers, Inc., must decide whether to build a small or a large facility at a new location in Fairfax. Demand at the location will either be low or high, with probabilities 0.3 and 0.7,respectively. If Cheryl builds a small facility and demand proves to be high, she then has the option of expanding the facility. If a small facility is built and demand proves to be high, and then the retailer expands the facility, the payoff is $230,000. If a small facility is built and demand proves to be high, but Cheryl then decides not to expand the facility, the payoff is $203,000. If a small facility is built and demand proves to be low, then there is no option to expand and the payoff is $250,000. If a large facility is built and demand proves to be low, Cheryl then has the option of stimulating demand through local advertising. If she does not exercise this option, then the payoff is $40,000. If she does exercise the advertising option, then the response to…arrow_forwardMachado Construction is considering two options for its supplier portfolio. Option 1 uses two local suppliers.

- A firm must decide whether to construct a small, medium, or large stamping plant. A consultant’sreport indicates a .20 probability that demand will be low and an .80 probability that demand willbe high.If the firm builds a small facility and demand turns out to be low, the net present value will be$42 million. If demand turns out to be high, the firm can either subcontract and realize the net present value of $42 million or expand greatly for a net present value of $48 million.The firm could build a medium-size facility as a hedge: If demand turns out to be low, its netpresent value is estimated at $22 million; if demand turns out to be high, the firm could do nothingand realize a net present value of $46 million, or it could expand and realize a net present value of$50 million.If the firm builds a large facility and demand is low, the net present value will be – $20 million,whereas high demand will result in a net present value of $72 million.a.

They are considering selling the new soda X-Mist during the upcoming summer season. The company believes, based on its limited market analysis, that there is a 0.75 probability that X-Mist will have a successful summer season and have estimated that they will receive a profit of $4 million if it is successful. If X-Mist is not successful over the summer season, the company will incur a loss of $900,000. The firm Market-Strategies can do an extensive market analysis for a fee of $35,000. Market-Strategies has demonstrated that it is 90 percent reliable in its market analysis for soft drinks, i.e., a soda that will be successful in the market will be reported as ‘Successful’ by Market-Strategies with a probability 0.9 and a soda that will not be successful in the market will be reported as ‘Fail’ by Market-Strategies with a probability of 0.9.
