Instructor Overview
Students begin to formalize their understanding of probability. They are introduced to the concept of probability as a measure of likelihood and how to calculate probability as a ratio. The terms discussed (impossible, certain, etc.) in Lesson 1 are given numerical values.
Key Concepts
 Students will think of probability as a ratio; it can be written as a fraction, decimal, or a percent ranging from 0 to 1.
 Students will think about ratio and proportion to predict results.
Goals and Learning Objectives
 Define probability as a measure of likelihood and the ratio of favorable outcomes to the total number of outcomes for an event.
 Predict results based on theoretical probability using ratio and proportion.
