Probability Unit Vocabulary

  1. Events for which the occurrence of one has no impact on the occurrence of the other.
    Independent Events
  2. All possible outcomes of a given experiment.
    Sample Space
  3. A subset of a sample space.
  4. An event consisting of just one outcome. A simple event can be represented by a single branch of a tree diagram.
    Simple Event
  5. A sequence of simple events.
    Compound Event
  6. The complement of event E, sometimes denoted E’ (E prime), occurs when E doesn’t. The probability of E’ equals 1 minus the probability of

    E: P(E’) = 1 – P(E).
  7. If an event A can occur in m ways and for each of these m ways, an event B can occur in n ways, then events A and B can occur in m n ways. This counting principle can be generalized to more than two events that happen in succession. So, if for each of the m and n ways A and B can occur respectively, there is also an event C that can occur in s ways, then events A, B and C can occur in m n s ways.
    Counting Principle
  8. A tree-shaped diagram that illustrates sequentially the possible outcomes of a given event.
    Tree Diagram
  9. The possible results of an experiment.
  10. The chance something will happen.
