Question

7. If A = { 1,2} & P(A) is a power set of a set A, Then find P(A).​

Answer 1

Answer:

And altogether we get the Power Set of {a,b,c}:

P(S) = { {}, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c} }

Think of it as all the different ways we can select the items (the order of the items doesn't matter), including selecting none, or all.
