{1, 3, 5} should be the union

Andreas Mann · Answer 2

A is the set of values 1, 2, and 3

B is the set of values 1, 2, 3, 4, 5, and 6

Basically notation A U B means this "A union B". So we just combine all of the values from both A and B into one giant set. Then we reamove all of the duplicates as with set notation, and only one unique value is allowed

Doing that leads to the answer {1, 2, 3, 4, 5, 6}

Plus since the numbers in set A also can be found in set B means that set A is a subset of set B. A U B = B
