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. The net expected value, if you chose to test only design A, is The net expected value, if you chose to test only design B, is The reservation price of design A is The reservation price of design B is
