3.1 Make predictions based on data collected and identify all possible outcomes of an event.

3.2 Determine an experimental estimate of the probability of simple events using frequency tables.

3.3 Determine the theoretical probability of simple events using percentages, fractions and decimals.

3.4 Systematically find all possible outcomes of an event using tree diagrams and organised lists.

3.5 Compare theoretical and experimental probabilities.

4.1 Develop and evaluate strategies to predict and win based on the relative frequency.

4.2 Investigate, make and justify the probability of events in common situations.

4.3 Find and check theoretical probability through trials.

4.4 Theoretically and experimentally examine the probabilities of games of chance and how to make an unfair game fair.

4.5 Use tree diagrams to find the possible outcomes for a sequence of events.

4.6 Describe the notion of "short run variability" and explain why probability is not an accurate predictor of events​.
