Philip witt, president of witt input devices, wishes to create a portfolio of local supplier for his new line of keyboards. as suppliers all reside in a location prone to hurricanes, tornadoes, flooding, and earthquakes, philip 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 total shutdown would cost the company approximately $520,000.$ he estimates the "unique event" rish for any of the suppliers to be $7\%.$ assuming that the marginal cost of managing an additional suppler is $14800$ per year, how many suppliers should witt input devices use? assumer that up to three nearly identical supplers are available.
