WebProbability Formulas The Single Event Probability Calculator uses the following formulas: P (E) = n (E) / n (T) = (number of outcomes in the event) / (total number of possible outcomes) P (E') = P (not E) = 1 - P (E) Where: P (E) is the probability that the event will occur, P (E') is the probability that the event will not occur, WebRule 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. dave harmon plumbing goshen ct
