Probability: possible outcomes

  • Probability

Description

This unit introduces and explores the concept of liklihood as a relative measure, and demonstrates multiple ways to represent likelihood such as Venn diagrams, tree diagrams and two-way tables.

This unit is the first introduction to probability and likelihood. Pupils develop their understanding of how likely something is, looking at relative likelihoods and displaying outcomes but without formalising probability using measurable numerical values at this stage. Pupils explore different ways to display outcomes to gain a sense of what it means to say something is likely or unlikely in preparation for more calculative methods and theoretical probability in the next unit.

  1. Equally likely outcomes
  2. Non-equally likely outcomes
  3. The scale of likelihoods
  4. Experiments to determine how likely an outcome is
  5. Using lists to display outcomes for two events
  6. Using two-way tables to display outcomes for two events
  7. Using an outcome tree to display outcomes for two events
  8. Using a Venn diagram to display outcomes for two events
  9. Comparing representations of outcomes for two events
  10. Using lists to display outcomes for more than two events
  11. Using an outcome tree to display outcomes for more than two events
  12. Using a Venn diagram to display outcomes for more than two events
  13. Comparing representations of outcomes for more than two events
  14. Problem solving with possible outcomes
