Set A and the universal set U are defined as follows.

Part (a)

<h3>Answer: Ø</h3>

This is the empty set

------------------

Explanation:

It doesn't matter what set A is composed of. Intersecting any set with the empty set Ø will always result in the empty set.

This is because we're asking the question: "What does some set A and the empty set have in common?". The answer of course being "nothing" because there's nothing in Ø. Not even the value zero is in this set.

We can write Ø as { } which is a set of curly braces with nothing inside it.

Part (b)

<h3>Answer: {1,2,3,4,5,6}</h3>

-----------------

Explanation:

When you union the universal set with any other set, you'll get the universal set.

The rule is $A \cup B = B$ where I've made B the universal set to avoid confusion of the letter U and the union symbol $\cup$ which looks nearly identical.

Why does this rule work? Well if an item is in set $\overline{A}$ , then it's automatically in set U (everything is in set U; it's the universe). So we're not adding anything to the universe when applying a union involving this largest set.
