Lesson details
Key learning points

- Outcomes that are not equally likely can be identified and compared
- Factors can be identified that can cause one outcome to be more/less likely than another
Keywords
Event - An event is a subset of a sample space. It could be a particular outcome or be a set of outcomes that may occur from a trial.
Common misconception
The outcomes of a trial are always equally likely to occur (e.g. each of the two players in a tennis match are equally likely to win).
There are factors that may affect how likely one outcome is compared to another (e.g. the skill or experience of one tennis player compared to the other).

Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
