Determine probabilities using matching outcomes/total outcomes.
Understand the concept of a ‘sample space’. Identify the sample space for both a single event and two combined events (eg adding two dice) and use to calculate probabilities.
Understand the difference between experimental and theoretical probabilities. Calculate experimental probabilities/relative frequencies and estimate the most likely count given the number of trials and a probability.
KS3 Maths Curriculum Area
Understand that the probabilities of all possible outcomes sum to 1
Generate theoretical sample spaces for single and combined events with equally likely, mutually exclusive outcomes and use these to calculate theoretical probabilities
