Permutations and combinations
What this topic asks you to be able to do
- know what the terms permutation and combination mean, and work through straightforward problems that involve making selections
- solve problems on arranging objects in a line, including ones with repetition (e.g. how many ways the letters of the word ‘NEEDLESS’ can be arranged) and ones with restriction (e.g. how many ways several people can line up when two given people must, or must not, be side by side)
