| 4.3 | Independence |
- Key Idea 1: Two events are independent if the occurrence of one has no influence on the chance of the occurrence of the other...
- For example, if you toss a coin and roll a die, the outcomes of the two activities are clearly independent.
- Tosses of distinct coins are independent.
- Repeated tosses of the same coin are independent.
- But the occurrences of rainfall in Chicago and Milwaukee (less than 100 miles apart) are not likely to be independent.
