### NC information

P3 relate relative expected frequencies to theoretical probability, using appropriate language and the 0-1 probability scale

P7 construct theoretical possibility spaces for single and combined experiments with equally likely outcomes and use these to calculate theoretical probabilities

P8 __calculate the probability of independent and dependent combined events, including using tree diagrams and other representations, and know the underlying assumptions__

N5 apply systematic listing strategies **including use of the product rule for counting (i.e. if there are ***m ***ways of doing one task and for each of these, there are ***n ***ways of doing another task, then the total number of ways the two tasks can be done is ***m *Ã— *n ***ways)**
