Question

If A = {1, 2, 3) and B = {1, 2, 3, 4, 5, 6, 7, 8) then AUB

O {1, 2, 3)
O {1, 2, 3, 4, 5, 6, 7, 8)

Answer 1

The correct answer is {1, 2, 3, 4, 5, 6, 7, 8}

Explanation:

Let's recall that the union of two sets A and B is defined as the set of all the elements that are in set A or in set B. The union of two sets denotes as A ∪ B. In this case, all the elements of set A are included in set B. That's why the correct answer is set B {1, 2, 3, 4, 5, 6, 7, 8}
