Let $S = \{ 0,\,1,\,5,\,4,\,7\} $. Then the total number of subsets of $S$ is
$64$
$32$
$40$
$20$
(b) $S = \,\,\,\,\{ 0,\,1,\,5,\,4,\,7\} $,
then, total number of subsets of $S$ is ${2^n}$.
Hence, ${2^5} = 32$.
Which of the following are sets ? Justify your answer.
The collection of all natural numbers less than $100 .$
What universal set $(s)$ would you propose for each of the following :
The set of right triangles
Set $A$ has $m$ elements and Set $B$ has $n$ elements. If the total number of subsets of $A$ is $112$ more than the total number of subsets of $B$, then the value of $m \times n$ is
Write down all the subsets of the following sets
$\{ a\} $
