BOB, Probability

Now probability unit is ending up. I actually understand it now, but I need a little more thinking about the questions so I can solve it. I also need questionnaires to practice on my self maybe, the review questions in our text book will do. It really confuses me sometimes about the questions, because it twists' my brains. I really need to review just in order for me to get at least 50 percent oh well. I will try and squish my brains, and that's it.
