11. Evaluate the intersection property

If $X$ $=$ $\{$$x$ : $x$ $=$ $3^n$, $n \in \mathbb{W}$ and $n \le 3\}$, $Y$ $=$ $\{$$x$ : $x$ $=$ $3n$, $n \in \mathbb{N}$ and $n \le 4\}$ and $Z$ $=$ $\{$$0$, $1$, $3$, $9$, $10$$\}$, then select the associative property of intersection of sets and evaluate the following:

 

(i) Associative property of intersection of sets: $X \cup (Y \cap Z) = (X \cap Y) \cap Z$$X \cap (Y \cap Z) = (X \cap Y) \cap Z$$X \cup (Y \cup Z) = (X \cup Y) \cup Z$$X \cap (Y \cap Z) = (X \cup Y) \cup Z$.

 

(ii) $X \cap (Y \cap Z)$  $=$ $\left\{i,i\right\}$.
