This formula is similar to the non-overlapping events, but we … WebbRule 1: The probability of an impossible event is zero; the probability of a certain event is one. Therefore, for any event A, the range of possible probabilities is: 0 ≤ P (A) ≤ 1. Rule 2: For S the sample space of all possibilities, P (S) = 1. That is the sum of all the probabilities for all possible events is equal to one.
