(i) Subsets of {a} are

(i) Subsets of {a} areΦ and {a}.

(ii) Subsets of {a, b} are

Φ, {a}, {b}, and {a, b}.

(iii) Subsets of {1, 2, 3} are

Φ, {1}, {2}, {3}, {1, 2}, {2, 3}, {1, 3}, and {1, 2, 3}.

(iv) Only subset of Φ is Φ.

Answer 2

Step-by-step explanation:

(i) The subsets of {a} are ϕ and {a}.

(ii) The subsets of {a,b} are ϕ,{a},{b},and{a,b}.

(iii) The subsets of {1,2,3} are ϕ,{1},{2},{3},{1,2},{2,3},{1,3},and{1,2,3}

(iv) The only subset of ϕ is ϕ.
