**True or False?**

\(\quad \quad \quad\) \(|X^C \cup Y^C \cup Z^C| = |(X \cap Y \cap Z)^C|\)?

If **X** and **Y** are two sets, **X \(∩\) \((Y∪X)^c\)** is equal to

**Details** **and** **assumptions**:

\(\rightarrow\) **\(∩\)** represents intersection.

\(\rightarrow\) **\(∪\)** represents union.

\(\rightarrow\) \(X^c\) represents compliment of set X.
