1.

Write down all the subsets of the following sets: (i) {a} (ii) {a, b} (iii) {1,2,3} (iv) (-1,0,1}

Answer»

(i) Subsets of {a} are {a}, φ

(ii) Subsets of {a, b} are {a, b},φ,{a},{b}

(iii) Subsets of {1, 2, 3} are {1, 2, 3}, are {1}, {2}, {3}, {1,2}, {2, 3}, {3,1}

(iv) Subsets of {-1, 0, 1} are {-1, 0, 1}, φ, {-1}, {0}, {1}, {-1,0}, {0,1}, {-1,1}
