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, ${2^5} = 32$.
Are the following pair of sets equal ? Give reasons.
$A = \{ 2,3\} ,\quad \,\,\,B = \{ x:x$ is solution of ${x^2} + 5x + 6 = 0\} $
Write the following sets in the set-builder form :
${\rm{\{ 2,4,8,16,32\} }}$
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:
$\phi \,….\,B$
List all the elements of the following sers :
$D = \{ x:x$ is a letter in the word $"\mathrm{LOYAL}" $ $\} $
Examine whether the following statements are true or false :
$\{ a,b\} \not\subset \{ b,c,a\} $
