1. What is the sample space of an experiment?
2. Using the language of sets and assuming that A and B are events in a sample space S, write the following events in set notation: (A or B); (A and B); not A.
3. In a sample space, what is the probability of the empty set?
4. What subset in a sample space corresponds to the certain event?
5. Write a formula for the probability of the event A ´ B, assuming that you know Pr (A), Pr (B), and Pr (A ¨ B).
6. Explain the difference between mutually exclusive events and independent events
