**Grade 12 Precalculus Module 5 Lessons 9–10**

Well, what did you expect? How do expected value and the average sum of an event compare? Ms. Wilson guides you through two lessons on discrete probability distributions and the connection between actual results and expected results when calculating probabilities. You will need paper, a pencil, and a calculator. If you have access to a workbook, or a printer, we also suggest using the Classwork for the lesson, which is available using the link below the video.
