8 subsets
The number of subsets can be calculated from the number of elements in the set. So if there are 3 elements as in this case, there are: 23=8 subsets. Remember that the empty (or null) set and the set itself are subsets.

Can 0 be a subset?

The role of 0 among sets is analogous to the role of zero in a number system. Every nonempty set has at least two subsets, 0 and itself. The empty set has only one, itself. The empty set is a subset of any other set, but not necessarily an element of it.

Does every set have a proper subset?

Any set is considered to be a subset of itself. No set is a proper subset of itself. The empty set is a subset of every set. The empty set is a proper subset of every set except for the empty set.

How many subsets are there in a set?

So a set with two elements has 4 subsets. OK, let’s be more systematic now, and list the subsets by how many elements they have: Subsets with two elements: {apple, banana}, {apple, cherry}, {banana, cherry}

What are all the subsets of the set?

In mathematics, the power set (or powerset) of any set S is the set of all subsets of S, including the empty set and S itself, variously denoted as P ( S ), 𝒫( S ), ℘( S) (using the ” Weierstrass p “), P(S), ℙ(S), or, identifying the powerset of S with the set of all functions from S to a given set of two elements,…
