Question

What does union mean in a statistics problem?

Answer 1

Explanation:

The union of two sets is the set of elements that belong to one or both sets.

Symbolically, the union of X and Y is denoted by X ∪ Y. As an example, suppose set A = {1, 2, 3} and set B = {1, 3, 5}.

Then, the union of sets A and B would be {1, 2, 3, 5}.
