Ø
0
1 2 3

Answer 1

Option (b) is correct.

0 is not a subset of set {1,2,3}

Explanation:

Given : The set {1, 2, 3}

We have to choose the correct options out of given options that is not a subset of given set {1,2,3}

Consider the given set {1, 2, 3}

A set is called a subset if all elements of the subset are elements of the set. and number of subset is given by the formula
`2^n`

Thus, for the given set {1, 2, 3}

The subsets are {1}, {3}, {5}, {1, 3} , {1, 2}, {2,3} , {1,2,3}, Ф

Thus, from the given options only 0 doesnot belong to the subset of set {1,2,3}

Thus, 0 is not a subset of set {1,2,3}

Answer 2

0 is not in the set, so 0 cannot be a subset.
