What to Focus On

  • A random experiment has more than one possible outcome.
  • The exact outcome cannot be predicted in advance.
  • A coin has two outcomes: Head and Tail.

  • An event can have one or more outcomes.
  • An elementary event has exactly one outcome.
  • The event "even number on a die" is not elementary because it has three outcomes.

  • Use favourable outcomes in the numerator.
  • Use all possible outcomes in the denominator.
  • The formula applies when outcomes are equally likely.

Common Mistakes to Avoid

An event and an outcome are the same thing.

An elementary event can contain more than one outcome.

Probability can be greater than 1 or less than 0 if the event seems very likely or very unlikely.
