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. WebFormal addition rule. P (A or B) = P (A) + P (B) - P (A and B) Intuitive addition rule. To find P (A or B), find the sum of the number of ways event A can occur and the number of ways event B can occur, adding in such a way that every outcome is counted only once. P (A or B) is equal to that sum, divided by the total number of outcomes in the ...
