Probability Models
1. In statistics, what is a sample space?
2. In statistics, what is an event?
3. Explain why the probability of any event is a number between 0 and 1.
4. What is the sum of the probabilities of all possible outcomes?
5. What is meant by the complement of an event?
6. When are two events considered disjoint?
7. Explain the difference between disjoint and independent.
8. What is the Multiplication Rule for independent events?
9. Draw a Venn diagram that shows the union of two events. Then draw one that shows the
intersection.
