Sets Operations

Definition: The power set $P (A)$ is the set containing all possible subsets of $A$ .
List Subsets: For $A = {1, 2}$ , the subsets are:
- Empty set: $\emptyset$
- Singletons: ${1}, {2}$
- The set itself: ${1, 2}$
Count: There are exactly 4 elements in $P (A)$ .
Formula Verification: $2^{n (A)} = 2^{2} = 4$ .
