Lesson Details
Key learning points
- A set of possible outcomes can be stated.
- Outcomes can be evaluated to decide how likely they are.
- Outcomes with the same likelihood can be identified.
Common misconception
Rolling a 6 on a dice is less likely to happen than rolling other numbers. Or ticket 001 is less likely to be drawn in a raffle than other tickets.
The random nature of picking a raffle or rolling a dice means all outcomes are equally likely as each other.
