What to Focus On

  • A random experiment has more than one possible outcome.
  • The outcome of a random experiment cannot be predicted in advance.
  • The sample space S is the set of all possible outcomes.

  • A deck has 52 cards.
  • There are 4 suits and 13 ranks in each suit.
  • There are 26 black cards and 26 red cards.

  • An event is a subset of the sample space.
  • The sure event is S.
  • The impossible event is φ.

Common Mistakes to Avoid

A sure event and an impossible event are the same because both feel like special cases.

An elementary event means an event with a small number of outcomes, not exactly one outcome.

Mutually exclusive and exhaustive events mean the same thing.

Memory Tips

Experiment and random experiment

Sample space S
