The instructor has given no indication about which case is most Iikeiy to be included on the exam. Unexpected travel fora fob interview has limited Raguei's study time in preparing for nal exams. and she has not had time to read the cases. She feels prepared for the other mate rial to be covered on this exam. and based on her experience on d1e other tesls. she believes she will miss at most 3 poinE on questions related to this other material.

The rst strategy is to spend one hour on each case. She believes that in doing this. she wiii be able to get 12 points out of the 25 possible regardless of which case is included on the exam. Another strategy is to seiect tin-nu of the three cases and spend one hour and thirty minutes on each of these. She believes that by doing this she will be able to get 2D poinE out of the possible 25 if either ofthese two cases is on the exam. A third strategy is to spend all three hours studying one case. If she does this and the case she studies is on the exam. she believes that she Il'irill get all 25 point. If it is not selected. she will get zero poinis
