### Combinations, Permutations, and Elementary Probability

1 Combinations, Permutations, and Elementary Probability Roughly speaking, Permutations are ways of grouping things where the order is important. Combinations are ways of grouping things where the order is not important.

### CHAPTER 5: PROBABILITY, COMBINATIONS & PERMUTATIONS

© Roger Nix (Queen Mary, University of London) - 5.1 CHAPTER 5: PROBABILITY, COMBINATIONS & PERMUTATIONS Probability If an event can occur in n ways (i.e. there are n possible outcomes) and a particular result can occur in m ways, then the probability of the particular result occurring is m / n .
