Probability as Counting
Probability measures an event relative to a complete probability model; for equally likely discrete outcomes, it is the fraction of the sample space that is favorable.
What you'll learn
- Build a complete sample space of equally likely elementary outcomes.
- Represent an event as a subset of that sample space and calculate its probability as favorable outcomes divided by total outcomes.
- Distinguish equally likely elementary outcomes from summarized categories that may have different likelihoods.
