What to Focus On

  • Conditional probability is probability after new information is given.
  • P(E|F) = P(E ∩ F) / P(F), with P(F) ≠ 0.
  • The condition changes the effective sample space.
  • Joint probability can be found using conditional probability.
  • The rule works for dependent events and successive trials.
  • For three events, use P(E ∩ F ∩ G) = P(E)P(F|E)P(G|EF).
  • Independence is defined both by conditional probability and by product form.
  • Dependent events are simply non-independent events.
  • Independent and mutually exclusive are different concepts.

Common Mistakes to Avoid

Conditional probability can be used even when the given event has probability zero.

Independent events and mutually exclusive events mean the same thing.

To test independence, one check is enough.
