Listing outcomes
An outcome is one possible result. For one spinner, list the different colours it could land on: sections of the same colour give the same outcome, and a colour with only one section still counts. For two steps, such as a coin and a spinner, every outcome of the first can go with every outcome of the second, so a table has rows × columns cells. For a condition like 'a total of 5', count every cell that fits, in both orders.
