# Comparing representations of outcomes for 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

An outcome tree doesn't have a sample space.

Each representation of the outcomes of a trial have a sample space as a part of it. For an outcome table, the table itself is the sample space. For an outcome tree, a sample space must always be constructed after drawing the two layers of branches.

### Keywords

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

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