Year 12 – Standard 1

Relative frequency and probability
  • Recognise that probabilities range from 0 (impossible) to 1 (certain) and can be represented as fractions, decimals and percentages

  • Identify and define the sample space as the set of all possible outcomes of a chance experiment

  • Determine the number of outcomes for an experiment

  • Represent equally likely outcomes using arrays and tree diagrams to solve problems, involving replacement where applicable, in two-stage events

  • Use relative frequency as an estimate of probability

  • Recognise that increasing the number of trials produces relative frequencies that become closer in value to the theoretical probability

  • Examine the use of statistics and the associated probabilities in shaping decisions made by the media, governments and companies
