HSS-CP.B.9
High school — Use permutations and combinations to compute probabilities of compound events and solve problems.
A note on this mapping: The Common Core files permutations and combinations under probability rather than giving counting a home of its own; the counting techniques themselves are the content of this skill.
The skill that covers it
What a student should be able to do
- Apply the fundamental counting principle to a multi-stage choice.
- Use factorials to count the arrangements of a set of distinct objects.
- Choose between a permutation and a combination by asking whether order matters.
- Count arrangements with and without repetition and tell the two apart.
