Probability of Mutually Exclusive Events

By the end of this unit, students will be able to:

  1. understand that two events are mutually exclusive if only one can happen in any given experiment;
  2. understand that the probabilities of an exhaustive set of mutually exclusive events add up to 1;
  3. and use the addition law in calculating the probability of mutually exclusive events.

Curriculum Alignment: Key Stage 4: Probability

  • Calculate the probability of independent and dependent combined events, including using tree diagrams and other representations, and know the underlying assumptions
