Under which of these conditions would Bayes’s Theorem indicate that the prior probabilities should be revised, when the new information from the study is received? Select one: a. when the prior probability of high sales is equal to 1.0 b. when it has the same probability of giving the three indications, irrespective of the actual sales level c. when the prior probabilities are the same and the research has a 60% chance of correct indication d. under none of these conditions
