Examine whether the following statements are true or false :
$\{ x:x$ is an even natural number less than $6\} \subset \{ x:x$ is a natural mumber which divide $36\} $
True. $\{ x:x$ is an even natural mumber less than $6\} = \{ 2,4\} $
$\{ x:x$ is a natural number which divides $36\} = \{ 1,2,3,4,6,9,12,18,36\} $
What universal set $(s)$ would you propose for each of the following :
The set of right triangles
List all the elements of the following sers :
$C = \{ x:x$ is an integer ${\rm{; }}{x^2} \le 4\} $
Let $A=\{1,2,3,4,5,6\} .$ Insert the appropriate symbol $\in$ or $\notin$ in the blank spaces:
$ 2 \, ....... \, A $
Which of the following sets are finite or infinite.
$\{1,2,3 \ldots .\}$
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 $B$)
