HSS.CP.B.9: (+) Use permutations and combinations to compute probabilities of compound events and solve problems.
What you'll learn
- Apply the Fundamental Counting Principle to count the outcomes of a multi-stage process
- Distinguish situations where order matters (permutations) from those where it does not (combinations)
- Compute permutations, nPr = n! / (n - r)!, and combinations, nCr = n! / (r!(n - r)!)
- Use permutations and combinations to count favorable and total outcomes and compute probabilities of compound events
- Solve real-world counting and probability problems, such as lotteries, committees, and arrangements
