Using a Venn diagram to display outcomes for two events

I can systematically find all the possible outcomes for two events by using a Venn diagram.

Lesson details

Key learning points

  1. Possible outcomes for two events can be shown in a Venn diagram.
  2. The Venn diagram can be used to generate any of the other models.
  3. Any of the other outcome diagrams can be used to generate a Venn diagram.

Common misconception

Pupils may not draw the rectangle in their Venn diagrams.

Refer back to the rectangle hosting all possible outcomes; the sample space and therefore a vital part of a Venn diagram.

Keywords

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

Although Venn diagrams are typically drawn using circles, rectangles can be used for ease on squared paper/workbooks.
