Lesson Details
Key learning points
- Knowledge of probability can be applied to real world situations .
- Probabilities can be used to aid decision making.
- Theoretical probabilities come from long-term behaviour and therefore may not be seen in the short-term.
Common misconception
When increasing a probability by 50%, pupils may choose to add 50% onto the existing probability rather than multiplying by 1.5.
Make links to any previous work pupils may have done on increasing by a percentage and emphasise that a percentage increase is being applied to the probability.
Keywords
Sample space - A sample space is all the possible outcomes of a trial. A sample space diagram is a systematic way of producing a sample space.
Tree diagram - Tree diagrams are a representation used to model statistical/probability questions. Branches represent different possible events or outcomes.
Outcome table - An outcome table is a table that shows all the possible outcomes.
