2. Sample space: 2 dice

5. Data on prison sentences

6. Empirical probabilities from prison sentence data

7. Data on endangered species

8. Empirical compound probabilities from endangered species data

9. Addition rule for mutually exclusive events

10. General additional rule (events not mutually exclusive – we don’t want to double-count the overlap, so we subtract it off once

11. Example of non-mutually exclusive events using the endangered species data: A = reptiles, B = U.S., so A&B = reptiles in the U.S.

12. Classical probability example of addition rule with mutually exclusive events (a) and non-mutually exclusive events (c)

13. Finishing off example from last slide

14. A similar example

15. … and finishing that one off.
