  • Probability: Complement

    Math is Fun · Teaching · Opens on the provider website

    Free teaching page defines the complement as every outcome not in event A, shows that an event and its complement make the complete sample space, and calculates P(not A) as 1 minus P(A).

  • Student-Led Probability Worksheet
