Question

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 or e)

Answer 1

p(a) = 0.2 and p(e) = 0.2, if uniform. Since the five outcomes are mutually exclusive, the probability of one of the other is 0.4.
