Write the following intervals in set-builder form :
$\left[ {6,12} \right]$
$\left[ {6,12} \right] = \{ x:x \in R,6\, \le \,x\, \le 12\} $
State which of the following sets are finite or infinite :
$\{ x:x \in N$ and ${x^2} = 4\} $
Let $A=\{a, e, i, o, u\}$ and $B=\{a, i, u\} .$ Show that $A \cup B=A$
Which set is the subset of all given sets
Which of the following sets are finite or infinite.
$\{1,2,3, \ldots 99,100\}$
Let $S=\{1,2,3,4\}$. The total number of unordered pairs of disjoint subsets of $S$ is equal to
