For each event a, one assigns the probability, which is denoted by pa and which is a real number in 0,1. This last example illustrates the fundamental principle that, if the event whose probability is sought can be represented as the union of several other events that have no outcomes in common at most one head is the union of no heads and exactly one head, then the probability of the union is the sum of.
