Answer 1

Answer:

Set Operations

Within that sample space, suppose we define two subsets as follows: X = {1, 2} and Y= {2, 3, 4}. The union of two sets is the set of elements that belong to one or both of the two sets. Thus, if X is {1, 2} and Y is {2, 3, 4}, the union of sets X and Y is: X ∪ Y = {1, 2, 3, 4}
