Write down all the subsets of the following sets

(i) Given that,

{a}

To write the subset of the given sets

A set A is said to be a subset of B if every element of A is also an element of B

A ⊂ B if a ∈ A,a ∈ B

Subsets of {a} are Φ and {a}

(ii) Given that,

{a, b}

To write the subset of the given sets

A set A is said to be a subset of B if every element of A is also an element of B

A ⊂ B if a ∈ A,a ∈ B

Subsets of {a, b}  are Φ {a}, {b}, and {a, b}.

(iii) Given that,

 {1, 2, 3}

To write the subset of the given sets

A set A is said to be a subset of B if every element of A is also an element of B

A ⊂ B if a ∈ A,a ∈ B

Subsets of  {1, 2, 3}  are  Φ, {1}, {2}, {3}, {1, 2}, {2, 3}, {1, 3}, and {1, 2, 3}.

(iv) Given that,

Φ

To write the subset of the given sets

A set A is said to be a subset of B if every element of A is also an element of B

A ⊂ B if a ∈ A,a ∈ B

Subsets of Φ is Φ.
