Union of Set(A Union B) or AUB Calculation
Set is the relation of some given data and has functions such as union and intersection. The term union means it is a collection of sets containing distinct elements. It is denoted by ∪.
The union of set A and set B is represented by A U B and it is pronounced as A union B. The union set contains the elements that belong to either A or to B or to both. The element is written only once even if they exist in both the sets for example: The two sets of events A={1, 2, 3} and B={3, 4, 6, 7, 8} these events are combined then we get : A U B = {1, 2, 3, 4, 6, 7, 8}
