L-1 Addition theorem of probability || mutual exclusive परस्पर अपवर्जी || class12th ||

Описание: ability states that for any two events, A and B, the probability that at least one of them will occur is the sum of their individual probabilities minus the probability of both occurring together
The General Addition Rule for Probability is given by P(A or B) = P(A) + P(B) - P(A and B) where A and B are the two events. For mutually exclusive events, P(A and B) = 0. So P(A or B) = P(A) + P(B) for mutually exclusive events.
