Key tips from Studyit:
  • You may be expected to complete probability trees and use these to find probabilities for any level of achievement.
  • Multiply the probabilities along the branches of tree diagrams if you are asked for the probability that an event AND another event occur.
  • Add the probabilities at the end of the branches if you are asked for the probability that an event OR another event occurs.
  • Probabilities are best written as fractions, but may be written as a decimal or percentage. If written as a percentage, you must include the percentage sign.
  • Probability must not be written as a ratio.
  • Be familiar with outcomes based on using dice, coins, and playing cards.
  • Read questions carefully and check that you have answered what is asked.
  • If you are asked to justify your reasons, a good way to answer clearly is to clearly bullet point your statements.
  • Show all working as credit may be given for a minor slip, if the assessor can see what you have done.
  • Attempt all questions as evidence from higher level questions may be used in awarding credit for a lower grade.
  • Revise how to interpret measures of centre, measures of spread, and statistical graphs and tables.
