Unit focus
- Likelihood depends on the possible outcomes and conditions. Events are independent when one result does not change the chance of the next; they are dependent when the first event changes the available outcomes or conditions.
- Use this routine: Define experiment → List complete outcomes → Compare favourable outcomes → Order likelihood → Check replacement/conditions → Classify dependence.
- Watch for likely confused with certain: A likely event can still fail to occur.
