Your role is to compute the expected value for the "Reject Christ" decision and pick the "best" choice to make.
The expected value concept is important and used in Decision Analysis. Decision Analysis can help make decisions based on the probability of different sates of nature from occurring, with different events from each decision being assigned a monetary value. The analysis computes the expected value of each decision, and identifi
