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.

WebThe probability calculator finds the probability of two independent events A and B occurring together. Two events are independent events if the occurrence of one event does not affect the probability of the other event. If A and B are independent events, then the probability of A and B occurring together is given by. P (A ∩ B) = P (B ∩ A ...
