which figure is the answer?

Deborah Kellogg buys Breathalyzer test sets for the Denver Police Department. The quality of the test sets from her two suppliers is indicated in the following table: Percent Probability for Winter Defective Park Technology 1% 0.70 0.25 5% 0.05 Probability for Dayton Enterprises 0.25 0.25 0.50 3% For example, the probability of getting a batch of tests that are 1% defective from Winter Park Technology is 0.70. Because Kellogg orders 10,000 tests per order, this would mean that there is a 0.70 probability of getting 100 defective tests out of the 10,000 tests if Winter Park Technology is used to fill the order. A defective Breathalyzer test set can be repaired for $0.60. Although the quality of the test sets of the second supplier, Dayton Enterprises, is lower, it will sell an order of 10,000 test sets for $25 less than Winter Park. a) The correct decision tree (with EMVs rounded to the nearest whole number)for Deborah is shown in FIGURE 1 - 60 1% D(0.70) Buy from Winter Park 3% D(0.25) 102 - 180 300 5% D(0.05) 102 1% D(0.25) 60 tive be + $25 - 210 13% D(0.25) ellan 180 Buy from Dayton - 300 5% D(0.50) D = Defective Rate FIGURE 2 1% D(0.70) Buy from Winter Park 3% D(0.25) 102 - 60 - 180 - 300 5% D(0.05) - 102 1% D(0.25) - 60 3% D(0.25) 210 180 + $25 Buy from Dayton - 300 5% D(0.50) D = Defective Rate FIGURE 3 1% D(0.70) Buy from Winter Park - 60 3% D(0.25) 102 - 180 - 300 5% D(0.05) 102 1% D(0.25) - 60 3% D(0.25) 210 - 180 + $25 Buy from Dayton - 300 5% D(0.50) D = Defective Rate
