Suppose that an experiment has five separate mutually exclusive outcomes: A, B, C, D, and E. If the sample space for the experiment is a uniform sample space, what is P (A, B or E)?

  P(A∪B∪E) =P(A)+P(B)+P(E)

  You're welcome! Note that the probabilities can be added only if the events are mutually exclusive, as specified in the question.
