For the remaining questions, consider the following setting. We only need one design, and have available two alternative designs A and B. Assume that it costs $20 to test A, and it costs $14 to test B. We expect that, upon testing A, the outcome will be $80 with 40% chance, or will be $10 with remaining 60% chance. And on testing B, the outcome will be $60 with 50% chance, or will be $0 with remaining 50% chance. Using a decision-tree, find the expected value from testing A and then testing B (if needed) Question 9 Using a decision-tree, find the expected value from testing B and then testing A (if needed)
