WebThe union of two sets contains all the elements contained in either set (or both sets). The union is notated A ⋃ B. More formally, x ∊ A ⋃ B if x ∈ A or x ∈ B (or both) The … WebFirst we consider two sets, Set A A A and Set B B B. The union of Set A A A and Set B B B will result to a set which consists of all values or elements in both Set A A A and Set B B B. The union of the two sets can be denoted by A ∪ B A \cup B A ∪ B. Similar elements are only listed once. For example, we let:
