Addition Rule 1: When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event.P(A or B) = P(A) + P(B)Let’s use this addition rule to find the probability for Experiment 1....
Rule of Addition The probability that Event A or Event B occurs is equal to the probability that Event A occurs plus the probability that Event B occurs minus the probability that both Events A and B occur. P(A ∪ B) = P(A) + P(B) - P(A ∩ B) Note: Invoking the fact that...

How do you use the addition rule for probability? For mutually excusive events, one must add the probabilities of each event to happen. For non-mutually exclusive events, one needs to add the probabilities for each event to happen and subtract it from the probability of the events happening ...
What is the probability that when a pair of dice is rolled, at least one die shows a 3 or the dice sum to 8?Addition Rule of Probability:This rule is used to find the probability of the union of events. Mathematically, for two events, say {eq...

Addition Rule of Probability:a rule used to determine the probability of either event occurring. It is calculated by adding the probabilities of each of the two events then subtracting the probability of both events happening at the same time. ...
