3.9 Expectation

R4 Probability

	Content	Additional information
R4.1	understanding that uncertain outcomes can be modelled as random events with estimated probabilities	knowing that the probabilities of an exhaustive set of outcomes sum to one
R4.2	applying ideas of randomness, fairness and equally likely events to calculate expected outcomes

R5 Diagrammatic representations

	Content	Additional information
R5.1	understanding and applying Venn diagrams and simple tree diagrams	understanding that $P (A)$ means the probability of event $A$ understanding that $P (A^{'})$ means the probability of not event $A$ understanding that $P (A \cup B)$ means the probability of event $A$ or $B$ or both understanding that $P (A \cap B)$ means the probability of event $A$ and $B$
