Question: is union and intersection of set?
Answer: The union is written as A∪B or “A or B”. The intersection of two sets is a new set that contains all of the elements that are in both sets. The intersection is written as A∩B or “A and B”. ... In the final column the union, A∪B, is equal to A and the intersection, A∩B, is equal to B since B is fully contained in A.
