01 / QUICK RECAP
Connect the ideas.
- Record the complete ordered outcome.
- Count equally likely elementary outcomes, not summary labels.
- Multiply along a path; add disjoint paths.
- Update the remaining collection without replacement.
- Inclusive or counts the overlap once.
- Relative frequency estimates, rather than guarantees, future outcomes.
