Question

Q2. List all the subsets of the set { –1, 0, 1 }.

Answer 1

Answer:

Given Set, Let, 'S'= {–1, 0, 1}

The power set is given by:

P(S)={ɸ, {–1},{0},{1},{–1,0},{–1,1},{0,–1}, {–1,0,1}

n[P(S)]=2³=8

Answer 2

Answer:

Total number of subsets = 2³ = 8

Now let us see the subsets

{ {-1},{0},{1},{-1,0},{1,0},{-1,1},{-1,0,1},{ } }
