You’ll learn

  • The probability scale is a line from 0 (impossible) to 1 (certain), with 0.5 in the middle (50-50)
  • Work out each probability, then mark it in the right place on the line
  • Exception to the usual fraction rule: turn each answer into a DECIMAL (2 decimal places) so it is easier to place
