$\wp(X)$ of $X$ consists of all the subsets of $X$.

## Amount of Elements in a Power Set
|
|
Lets say we have $|X|$:
|
|
$$|X| = |\{ 1, \, \dots, \, n \}|$$
|
|
The $\wp(X)$ would have $2^{n}$ elements in the set.
|
|
# Example
|
|
$$X = \{ 1, \, 2 \}$$
|
|
$$\wp(X) = \{ \emptyset, \, \{ 1 \}, \, \{ 2 \}, \, X \}$$ |
