Ch15 Student: ___________________________________________________________________________ 1. A probability distribution A. is a way of dealing with uncertainty. B. lists all possible outcomes and the corresponding probabilities of occurrence. C. shows only the most likely outcome in an uncertain situation. D. both a and b E. both a and c 2. The variance of a probability distribution is used to measure risk because a higher variance is associated with A. a wider spread of values around the mean. B. a more compact distribution. C. a lower expected value. D. both a and b E. all of the above 3. Risk exists when A. all possible outcomes are known but probabilities can't be assigned to the outcomes. B. all possible outcomes are known and probabilities can be assigned to each. C. all possible outcomes are known but only objective probabilities can be assigned to each.

The maximin rule A. ignores bad outcomes. B. is used by optimistic managers. C. minimizes the potential regret. D. a and c E. none of the above 8. Using the minimax regret rule the manager makes the decision A. with the smallest worst-potential regret. B. with the largest worst-potential regret. C. knowing he will not regret it. D. that has the highest expected value relative to the other decisions. 9. In making decisions under risk A. maximizing expected value is always the best rule. B. mean variance analysis is always the best rule. C. the coefficient of variation rule is always best. D. maximizing expected value is most reliable for making repeated decisions with identical probabilities. E. none of the above The next 7 questions refer to the following: A firm is considering two projects, A and B , with the following probability distributions for profit. 10.
