# Comparing representations of outcomes for more than two events

I can identify the same outcome across all the different representations.

# Comparing representations of outcomes for more than two events

I can identify the same outcome across all the different representations.

## Lesson details

### Key learning points

- Fluency in moving between the representations is important.
- Sometimes it is better to display the outcomes using a particular representation.

### Common misconception

I can use outcome tables to categorise outcomes into as many events as I want.

Outcome tables are limited to categorising outcomes into only two events. You can use more tables to categorise outcomes into three or more events, but the number of tables you need quickly becomes massive!

### Keywords

Outcome table - An outcome table is a table that shows all the possible outcomes.

Tree diagram - Tree diagrams are a representation used to model statistical/probability questions. Branches represent different possible events or outcomes.

Outcome tree - Each branch of an outcome tree shows a possible outcome from an event or from a stage of a trial. The full outcome tree shows all possible outcomes.

Venn diagram - Venn diagrams are a representation used to model statistical/probability questions. Commonly circles are used to represent events.
