Subsets and Power Set
All subsets of a set and their number, with the solution.
What to find:
Separate elements with commas or spaces. For the count, n goes up to 1000.
This calculator lists all subsets of a set (the power set) and counts them.
|P(A)| = 2n
Each of the n elements is either in a subset or not, so there are 2ⁿ options. This count includes the empty set and the set itself.
Example. {a, b} has four subsets: ∅, {a}, {b}, {a, b}.
