Definitions:
Sample Space: The sample space is the set (or list) of all of the possible outcomes you have.
Ex: The sample space of rolling a fair dice is {1,2,3,4,5,6}
Probability Model: A probability model is a model you can create to simulate a real world event.
Ex: If you make 50% on your free throws, we can use a coin flip to model your shooting.
