Write the following as intervals :
$\{ x:x \in R, - 4\, < \,x\, \le \,6\} $
$\{ x:x \in R, – 4\, < \,x\, \le \,6\} = ( – 4,6]$
Consider the sets
$\phi, A=\{1,3\}, B=\{1,5,9\}, C=\{1,3,5,7,9\}$
Insert the symbol $\subset$ or $ \not\subset $ between each of the following pair of sets:
$A \ldots C$
$A = \{ x:x \ne x\} $ represents
Which of the following sets are finite or infinite.
$\{1,2,3, \ldots 99,100\}$
Let $S = \{ 0,\,1,\,5,\,4,\,7\} $. Then the total number of subsets of $S$ is
