01 / QUICK RECAP
Connect the ideas.
- Use equally likely complete outcomes when counting probabilities.
- Multiply stage choices; reduce available choices when repetition is not permitted.
- A condition restricts the denominator to the given group.
- Multiply conditional branches along a path and add disjoint paths.
- Replacement rules determine whether draw probabilities change.
- Simulation frequencies estimate probabilities and vary between finite runs.
