Question

15. Write the power sets of A = {a, b}.​

Answer 1

Answer:

Power set of A is P(A)={ ∅, {a},{b},{a,b}}

Step-by-step explanation:

Given set A={a,b}

number of elements of A=2

Therefore,n(A)=2

We know that :

If the number of elements of a set A is 'n' then number of subsets of A is 2^n

Number of subsets of A=2²=4

They are ∅, {a},{b},{a,b}

Power set of A is P(A)={ ∅, {a},{b},{a,b}}
