That would be the union of set A and set B wouldn't it?

Right but union in math really just means the same thing as it does in English 'to join'.

Think of it like this A U B is like saying A joined with B. If A was a set of red marbles and B was a set of blue marbles what would the set of A U B consist of?

jesseabney Group TitleBest ResponseYou've already chosen the best response.0
blue and red

Correct. Joining them does not change their form to purple or something. We still have red and blue marbles. So apply that to a small set of numbers A={1,3,5} and B={2,4,6}. Now what is A U B?

Right now expand that to a larger set A={all even numbers} and B={all odd numbers}. Now what is A U B?

Right or {all numbers}. Now just apply the appropriate terminaology (i.e. that used in your question), and you have your answer.
