# TIMES Module 12: Statistics and Probability: chance, year 7 - teacher guide

TLF ID M009046

This is a 13-page guide for teachers. It continues the development of probability. A careful consideration of outcomes and equally likely outcomes is undertaken. In year 7, students revisit simple situations with a clear and easily listed number of possible outcomes that can, or may, be assumed to be equally likely. In these special, limited situations, they consider probabilities of events by applying the concept of equal chances for equal 'sizes' of events. For example, some are obtained as the number of equally likely outcomes/total number of equally likely outcomes, and some are obtained as area of region/total area. To link with year 6 experiences, they also collect data to compare observed frequencies with expected frequencies under the assumption of equally likely probabilities.
