WebThe preceding example demonstrates the general formula for the cardinality of the union of two sets A and B (when A and B might intersect), A È B = A + B − A ∩ B .. In adding the number of elements in A to the number in B, we count those elements common to A and B twice; these are the elements in the intersection A ∩ B. WebThe A intersection B formula talks about the cardinality of a set. The cardinal number of a set is the total number of elements present in the set. For example, if Set A = {1,2,3,4}, then the cardinal number (represented as n (A)) = 4. ... What is Union and Intersection of Sets?

WebThe intersection of X and Y is 3. Now, another common operation on sets is union. So you could have the union of X and Y. And the union I often view-- or people often view-- as "or." So we're thinking about all of the elements that are in X or Y. So in some ways you can kind of imagine that we're bringing these two sets together. WebNone of the following _____12.
