Multiple Choice

Refer to the following payoff table:

There is an option of paying $100 to have research done to better predict which state of nature will occur. When the true state of nature is S1, the research will accurately predict S1 60% of the time. When the true state of nature is S2, the research will accurately predict S2 80% of the time.
Given that the research is done, what is the joint probability that the state of nature is S2 and the research predicts S2?

• A) 0.08
• B) 0.16

Definitions:

Negative Reinforcement
