Read the narratives below and follow the directions for each. If you discover that the narrative is incomplete, make up reasonable explanations to complete the story. Supply these extra explanations along with your answers.

a. Samantha must decide which courses to register for this semester. She has a part-time job, and she is waiting to find out how many hours per week she will be working during the semester. If she works 10 hours or less per week, she will register for three classes, but if she works more than 10 hours per week, she will register for only two classes. If she registers for two classes, she will take one class in her major area and one elective. If she registers for three classes, she will take two classes in her major area and one elective. Use a decision table to represent this logic.

b. Jerry plans on registering for five classes this semester: English Composition, Physics, Physics Lab, Java, and Music Appreciation. However, he is not sure if these classes are being offered this semester or if there will be timing conflicts. Also, two of the classes, Physics and Physics Lab, must be taken together during the same semester. Therefore, if he can register for only one of them, he will not take either class. If, for any reason, he cannot register for a class, he will identify and register for a different class to take its place and that fits his time schedule. Use a decision table that shows all rules to represent this logic.
