Lesson details

Key learning points

  1. Outcomes can be listed systematically using an appropriate representation
  2. Outcomes can be placed on the probability scale
  3. A probability of 0 means the outcome is impossible and a probability of 1 means the outcome is certain

Keywords

  • Trial - A trial is a single predefined test.

  • Outcome - An outcome is a result of a trial.

  • Theoretical probability - A theoretical probability is a probability based on counting the number of desired outcomes from a sample space where all individual outcomes are equally likely.

Common misconception

Pupils may omit outcomes or include repetitions of the same outcomes in their lists.

For each problem, encourage pupils to be systematic with their ordering of outcomes.


To help you plan your year 11 maths lesson on: Checking and securing displaying outcomes, download all teaching resources for free and adapt to suit your pupils' needs...

Pupils could explore using different systems of ordering for the same problem and then check that they have the same number of outcomes in each list.
