Summation of ProbabilitiesIn a lot of situations we are interested in the occurrence of events that consist of several data points, rather than just one sample point. The most common examples are when we look for the probability that an outcome is larger or smaller than a particular value. The probability of the compound event is then the sum of probabilities of the sample points that comprise the event. There are several simple rules for calculating compound events.
