### NC information

National curriculum code and descriptions (partially) covered by the layers

P1 record, describe and analyse the frequency of outcomes of probability experiments using tables and frequency trees

P3Â relate relative expected frequencies to theoretical probability, using appropriate language and the 0-1 probability scale

P7Â construct theoretical possibility spaces for single and combined experiments with equally likely outcomes and use these to calculate theoretical probabilities

N5Â apply systematic listing strategiesÂ including use of the product rule for counting (i.e. if there areÂ mÂ ways of doing one task and for each of these, there areÂ nÂ ways of doing another task, then the total number of ways the two tasks can be done isÂ mÂ Ã—Â nÂ ways)
