3. Chapter 5
When we talk about probability, we are talking about a (mathematical) measure of how likely it is for some particular thing to happen
Probability deals with chance behavior
We study outcomes, or results of experiments
Each time we conduct an experiment, we may get a different result
Probability models the short-term behavior of experiments
