A=(a,b,c)
Step 1
The power set of a set S is the set of all subsets of S. The first subset will be set S itself. Next, find all subsets that contain one less element (in this case 2 elements). Continue with this process until finding all subsets including the empty set.
Power Set = {{a,b,c},{a,b},{a,c},{b,c},{a},{b},{c},{}}
