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

Consider the experiment of observing a sequence of Bernoulli trials until exactly r successes occur. Let the r.v. X denote the number of trials needed to observe the rth success. The r.v. X is known as the negative binomial r.v. with parameter p, where p is the probability of a success at each trial. The pmf of the negative b
