Let $T_{n}$ denote the set of all sequences over $\{ 0, 1, 2 \}$ of length $n$. If we pick an element $x$ in $T_{n}$ uniformly at random what is the expected number of $\text{1's}$ in $x?$

Which of the following statement(s) is/are true? For $k=69597$ and $x_{1}, x_{2}, \dots, x_{k} \in (0, \infty), \dfrac{x_{1}+ x_{2}+ \dots + x_{2^{k}}} {2^{k}} \leq (x_{1} x_{2} \dots x_{2^k})^{2^\frac{1}{k}} .$ ... $(n^{3} - n)$ is divisible by $3$ for all positive integers $n$.
