Test Yourself

In Chapter 4, you learned to use the rules of probability to calculate the chance that a particular event would occur. In many situations, you can use specific probability models to estimate the probability that particular events would occur.

### 5.1 Probability Distributions for Discrete Variables

A probability distribution for a variable summarizes or models the probabilities associated with the events for that variable. The form the distribution takes ...
