Question

(4) A = {1, 3, 2, 7} then write any three subsets of A.​

Answer 1

$\huge\bf{ \underline{Question}}$

$\sf{Find\:any\:three\:subset}$

$\huge\bf{ \underline{Answer}}$

{$\sf{1,3}$}{$\sf{3,2}$}{$\sf{2,7}$}

$\huge\bf{ \underline{Explanation}}$

$\mapsto\sf{Total\:no.\:of\:subset\:=\:\ (2)^{n}}$

$\mapsto\sf{Total\:no.\:of\:subset\:=\:\ (2)^{4}}$

$\mapsto\sf{Total\:no.\:of\:subset\:=\: 16}$

Answer 2

${\huge{\bold{\purple{\bigstar{\boxed{\boxed{\bf{Question}}}}}}}}$

• A = {1, 3, 2, 7} then write any three subsets of A.

${\huge{\bold{\purple{\bigstar{\boxed{\boxed{\bf{Solution}}}}}}}}$

Total no. of subsets = $2^n$

Total no. of subsets = $2^4$

Total no. of subsets = $16$

3 subsets = { 1 , 3} { 1 , 2} { 1 , 7}

$\sf{\bold{\red{\boxed{\boxed{Extra\:information}}}}}$

• A set A is a subset of another set B if all elements of the set A are elements of the set B.
• the set A is contained inside the set B.
• The subset relationship is denoted as A⊂B
