Examine whether the following statements are true or false :

$\{ 1,2,3\} \subset \{ 1,3,5\} $

The number of proper subsets of the set $\{1, 2, 3\}$ is

If $A$ and $B$ are any two non empty sets and $A$ is proper subset of $B$. If $n(A) = 4$, then minimum possible value of $n(A \Delta B)$ is (where $\Delta$ denotes symmetric difference of set $A$ and set $B$)

Let $A$ and $B$ be two non-empty subsets of a set $X$ such that $A$ is not a subset of $B$, then

List all the subsets of the set $\{-1,0,1\}.$
