This unit is very interesting and I get most of it. It's just that sometimes when it seems like you have the right answer, you don't..does that make any sense? What I mean by that is that a wrong answer can seem right as to the point where it looks possible so you end up getting the wrong answer. So multiple choice questions for this unit are pretty difficult. I really like the long answers where something is assumed given that an event happens, because they're a breeze. What's really hard to remember is that you always have to have the probability over the sample space and I always forget that. The pre-test was okay so I'm sure the test will be okay as well. Good luck everyone.
