Eight problems are listed below for you to use in review for the test. You must do at least 5, but you are certainly encouraged to do more than 5.
For any credit, you must show all of your thinking including drawings, write very neatly, and use probability notation. If you want to make certain you know the concepts, do not check answers until you have put work into your answers.
