Question
Chapter A, Problem 21P
Summary Introduction
Interpretation: The owner of P Automotive Dealers is trying to decide whether to expand his current facility. If he expands and customer demand turns weak, there is a chance he could lease part of his newly constructed facility to another dealer. If he doesn’t expand and strong demand occurs, he could attempt to lease another facility across town. The decision tree shown in Figure A8 needs to be analyzed and the best set of decisions and expected payoffs needs to be determined.
Figure A.8
Concept Introduction: The measure of likelihood that an event will happen, in a random experiment is called probability.
