Appendix C. Probability refresher

In this appendix we’ll go through some of the basic concepts of probability. The subject deserves more treatment than this appendix provides, so think of this as a quick refresher if you’ve had this material in the past but need to be reminded about some of the details. For someone who hasn’t had this material before, I recommend studying more than this humble appendix. A number of good tutorials and videos are available from the Khan Academy that can be used for self-study.^[1]
