#### PROBABILITY:H

**1. Record describe and analyse the frequency of outcomes of probability experiments using tables and frequency trees**

**2. Apply ideas of randomness, fairness and equally likely events to calculate expected outcomes of multiple future experiments**

**3. Relate relative expected frequencies to theoretical probability, using appropriate language and the 0 – 1 probability scale**

**4. Apply the property that the probabilities of an exhaustive set of outcomes sum to one; apply the property that the probabilities of an exhaustive set of mutually exclusive events sum to one**

**5. Understand that empirical unbiased samples tend towards theoretical probability distributions, with increasing sample size**

**6. Enumerate sets and combinations of sets systematically, using tables, grids, Venn diagrams and tree diagrams**

**7. Construct theoretical possibility spaces for single and combined experiments with equally likely outcomes and use these to calculate theoretical probabilities**

**8. Calculate the probability of independent and dependent combined events, including using tree diagrams and other representations, and know the underlying assumptions**

**9. Calculate and interpret conditional probabilities through representation using expected frequencies with two-way tables, tree diagrams and Venn diagrams.**
