Use the 0-1 probability scale as a measure of likelihood of random events, for example, ‘impossible’ with 0, ‘evens’ with 0.5, ‘certain’ with 1.

Record, describe and analyse the relative frequency of outcomes of repeated experiments using tables and frequency trees.
Use relative frequency as an estimate of probability.
Understand that relative frequencies approach the theoretical probability as the number of trials increases.
Calculate probabilities, expressed as fractions or decimals, in simple experiments with equally likely outcomes, for example flipping coins, rolling dice, etc.
Apply ideas of randomness and fairness in simple experiments.
Calculate probabilities of simple combined events, for example rolling two dice and looking at the totals.
Use probabilities to calculate the number of expected outcomes in repeated experiments.
