This lesson, students will:
- 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.

Probability
- 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
