Phillip Witt, president of Witt Input Devices, wishes to create a portfolio of local suppliers for his new line of keyboards. As the suppliers all reside in a location prone to hurricanes, tornadoes, flooding, and earthquakes, Phillip believes that the probability in any year of a "super-event" that might shut down all suppliers at the same time at least 2 weeks is 2%. Such a total shutdown would cost the company approximately $450,000. He estimates the "unique-event" risk for any of the suppliers to be 5%. Assuming that the marginal cost of managing an additional supplier is $15,500 per year, how many suppliers should Witt Input Devices use? Assume that up to three nearly identical local suppliers are available. Find the EMV for alternatives using 1,2, or 3 suppliers. EMV(1)=$ (Enter your response rounded to the nearest whole number.) EMV(2)=S (Enter your response rounded to the nearest whole number.) EMV(3)=S (Enter your response rounded to the nearest whole number.) Based on the the EMV value, the best choice is to use
