These quizzes practise concepts within this topic. Multiple-choice answers alone do not demonstrate drawing, conducting an investigation or using a digital tool.
Activities to practise beyond the quiz
- Supported by the guided activity; selecting an MCQ does not demonstrate this action.
- VC2M6P01-C01For equally likely outcomes, use the count of favourable outcomes divided by the total. Probability cannot be below zero or above one.
- VC2M6P01-C02Represent a probability as a decimal and use a stated chance model to predict a count across repeated trials.
- VC2M6P01-C03Multiply a decimal probability by 100 to express it as a percentage. The underlying likelihood does not change.
- VC2M6P01-C04Constructing scales and estimating contextual likelihood with a stated reason.
