Why it matters
- Counting outcomes helps you compute probability the right way.
- Permutations vs. combinations makes “order matters?” automatic.
- Binomial probability models repeated yes/no experiments.
- The bell curve explains normal distributions in real life.
- Mean and spread summarize data clearly and correctly.
- Reading data builds strong decision-making and test skills.
Tip: If order matters → permutation. If not → combination.
