Non-mutually-exclusive means that some overlap exists between the two events in question and the formula compensates for this by subtracting the probability of the overlap, P(Y and Z), from the sum of the probabilities of Y and Z. In theory the first form of the rule is a special case...
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....
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 ...

Addition Rule for Mutually Exclusive Events If eventsAandBaremutually exclusive, then the probability ofAorBis the sum of the probability ofAand the probability ofB. We write this compactly as follows: P(AorB) =P(A) +P(B) Generalized Addition Rule for Any Two Events ...
To find the union of two events that are non-mutually exclusive, use this formula:The probability of event A or B is equal to the probability of event A plus the probability of event B minus the probability of event A and B. Read Addition Rule of Probability | Formulas & Examples ...
A method for finding the probability that either or both of two events occurs.Addition Rule: If events A and B are mutually exclusive (disjoint), then P(A or B) = P(A) + P(B) Otherwise, P(A or B) = P(A) + P(B) – P(A and B) Example 1: mutually exclusive In a group...
