Webb7 apr. 2024 · a Intersection b Formula When two sets (M and N) intersect, then the cardinal number of their union can be calculated in two ways: 1. The cardinal number of their union is the sum of their cardinal numbers of the individual sets minus the number of common elements. n (M ∪ N) = n (M) + n (N) - n (M ∩ N) 2. WebbThe following Additive Rule of Probability is a useful formula for calculating the probability of A ∪ B. Additive Rule of Probability P(A ∪ B) = P(A) + P(B) − P(A ∩ B) The next example, in which we compute the probability of a union both by counting and by using the formula, shows why the last term in the formula is needed.
