Question

Given a = {1, 2, 3, 4, 5, 6, 7, 8, 9} and b = {2, 4, 6, 8} what is AUB?

Answer 1

AUB is the union of sets A and B.
It is a set that contains every element of set A and every element of set B.
Write a set that has all the numbers in both sets A and B. Be sure to write each number only once even if the number appears in both sets A and B.
