Probability
Determine probabilities for chance experiments
  • List the Loading  for Loading  experiments

  • Express the Loading  of an event, which has a finite number of equally likely Loading ,

    as Pevent=number of favourable outcomestotal number of outcomes

  • Recognise that probabilities range from 0 (impossible) to 1 (certain) and that equally likely outcomes have equal probabilities

  • Verify that the total of the probabilities of all possible outcomes of an event is 1

  • Identify and describe theoretical (expected) probabilities as being the likelihood of outcomes occurring under fair or unbiased conditions

  • Explain that observed probability is the Loading  resulting from repeated trials of a Loading  and determine observed probabilities

  • Explore relative frequencies by using a Loading  generator to repeat a chance experiment a number of times

Determine probabilities for complementary events
  • Identify and describe the complement of an event

  • Verify that the sum of the probability of an event and its complement is a total of 1

  • Solve problems involving the probability of Loading 

  • Represent the possible outcomes for complementary events in various forms
