Best ResponseYou've already chosen the best response.2Right but union in math really just means the same thing as it does in English 'to join'.

Best ResponseYou've already chosen the best response.2Think 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?

Best ResponseYou've already chosen the best response.2Correct. 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?

Best ResponseYou've already chosen the best response.2Right now expand that to a larger set A={all even numbers} and B={all odd numbers}. Now what is A U B?

Best ResponseYou've already chosen the best response.2Right or {all numbers}. Now just apply the appropriate terminaology (i.e. that used in your question), and you have your answer.
