Combinations vs Permutations | NCEA Level 3 Statistics Probability Explained

@Captain_Calc Combinations and permutations are two of the most important counting methods in NCEA Level 3 Statistics probability. In this video, I explain the difference between them, when to use each one, and how they connect to nCr, nPr, and factorials. This is aimed at students studying NCEA Level 3 Statistics, especially those preparing for the Probability Concepts external. We look at the key idea: Does order matter? If order matters, you are usually dealing with a permutation. If order does not matter, you are usually dealing with a combination. In this lesson, we cover: What a factorial means What permutations are What combinations are The difference between nPr and nCr How to decide which method to use Common NCEA-style wording Simple worked examples This is a great starting point before tackling harder probability questions involving selections, arrangements, committees, teams, passwords, races, and ordering problems.
