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 Loading  of a Loading  Loading 

  • Determine the number of outcomes for an experiment

  • Express the probability of an event that has a finite number of equally likely outcomes, as Pevent=number of favourable outcomestotal number of outcomes
  • Apply Pan event does not occur=1-Pthe event does occur to calculate the probability of the complement of an event
  • Represent equally likely outcomes using Loading  and Loading  to solve problems, involving replacement where applicable, in two-stage events

  • Use Loading  as an estimate of probability

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

  • Calculate the expected frequency of an event occurring using np where n is the number of times an experiment is repeated, and p is the probability that the event occurs each of those times
  • Examine the use of statistics and the associated probabilities in shaping decisions made by the media, governments and companies
