Question

Toppr Admin · Accepted Answer

Let A-1-2-3-Number of elements in A is 3Hence n-3Number of subsets of A-2n where n is the number of elements of the set A-23-8The subsets of -1-2-3- are-x3D5-1-2-3-1-2-2-3-1-3- and -1-2-3-

Write down all the subsets of the set {1, 2, 3}

Let $A = {1, 2, 3}$

Number of elements in $A$ is $3$

Hence $n = 3$

Number of subsets of $A = 2^{n}$ where $n$ is the number of elements of the set $A$

$= 2^{3} = 8$

The subsets of ${1, 2, 3}$ are

$ϕ$ , ${1}$ , ${2}$ , ${3}$ , ${1, 2}$ , ${2, 3}$ , ${1, 3}$ and ${1, 2, 3}$

Write down all the subsets of the set {1, 2, 3}

Let A={1,2,3}Number of elements in A is 3Hence n=3Number of subsets of A=2n where n is the number of elements of the set A=23=8The subsets of {1,2,3} areϕ,{1},{2},{3},{1,2},{2,3},{1,3} and {1,2,3}

Let $A = {1, 2, 3}$

Number of elements in $A$ is $3$

Hence $n = 3$

Number of subsets of $A = 2^{n}$ where $n$ is the number of elements of the set $A$

$= 2^{3} = 8$

The subsets of ${1, 2, 3}$ are

$ϕ$ , ${1}$ , ${2}$ , ${3}$ , ${1, 2}$ , ${2, 3}$ , ${1, 3}$ and ${1, 2, 3}$
