This is the first lesson in the Probability Unit for AP Statistics. In this lesson students will be exposed to important vocabulary, they will interpret theoretical probability, and use simulations to model chance behavior. These lessons are set up to have the teacher lead the students through the note-taking process while incorporating examples for the students to try. The answer keys are provided. Homework will be added shortly at not additional cost to those who purchase before. I will also be making videos that take the student through the lesson for those that flip their classroom or for absent students. SMART notebook files are included for the teacher to fill in with the class.
