- AC9M4P01 · Order outcomes by likelihoodDescribe everyday events and the outcomes of chance experiments, order them by how likely they are, and identify independent or dependent events.
- AC9M4P02 · Variation in chance experimentsRepeat chance experiments to observe how outcomes relate, then describe how the results vary.

What is probability?
Probability describes how likely an event is, from impossible to certain, and can be written as a fraction of the possible outcomes.
How to teach it
Order events from impossible to certain in everyday language, then quantify simple chances as fractions of the equally-likely outcomes.
In an Australian classroom
Chance language in the Australian curriculum is deliberately precise: certain, likely, unlikely and impossible come before fractions and percentages do.
Worked example
Common mistake
Assuming a rare-but-possible event is impossible, and thinking past results change the next independent outcome.
