Event outcome can mean that other outcomes cannot happen {disjoint events} {mutually exclusive events}|. For equally probable outcomes, outcome probability is 1/N, where N is number of mutually exclusive outcomes. To find probability of at least one of mutually exclusive outcomes, add all probabilities: P = p1 + p2 + p3 + ... + pN, where pi are probabilities, and N is outcome number.
