Make correct statements by filling in the symbols $\subset$ or $ \not\subset $ in the blank spaces:
$\{ 2,3,4\} \ldots \{ 1,2,3,4,5\} $
$\{ 2,3,4\} \subset \{ 1,2,3,4,5\} $
In the following state whether $\mathrm{A = B}$ or not :
$A = \{ 2,4,6,8,10\} ;B = \{ x:x$ is positiveeven integer and $x\, \le \,10\} $
Let $A=\{1,2,3,4,5,6\} .$ Insert the appropriate symbol $\in$ or $\notin$ in the blank spaces:
$ 2 \, ……. \, A $
If $Q = \left\{ {x:x = {1 \over y},\,{\rm{where \,\,}}y \in N} \right\}$, then
State which of the following sets are finite or infinite :
$\{ x:x \in N$ and $x$ is prime $\} $
$\{ x:x \in N$ and $x$ is odd $\} $
