Lesson Details
Key learning points
- Events with outcomes that are likely to not be equally likely can be identified
- 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
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).
Keywords
