The logic behind the addition rule for probabilities is that when P(A) and P(B) are added, the occasions on which A and B both occur are counted twice. To adjust for this, P(AB) is subtracted.

Subject 3. Addition Rule for Probabilities: the Probability that at Least One of Two Events Will Occur e or." In other words, either one event can occur or both events can occur.
Such probabilities are calculated using the addition rule for probabilities.
P(A or B) = P(A) + P(B) - P(AB)
<span>The logic behind this formula is that when P(A) and P(B) are added, the occasions on which A and B both occur are counted twice. To adjust for this, P(AB) is subtracted.
If events A and B are mutually exclusive, the joint probability of A and B is 0. Consequently, the probability that either A or B occurs is simply the sum of the unconditio
