The expected value for A is not 38 and the expected value for B is not 30

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. Question 3 The net expected value, if you chose to test only design A, is Question 4 The net expected value, if you chose to test only design B, is
