The null set is a proper subset of any non-empty set.
meaning of proper subsets
Nullset was created in 1997.
A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.
The empty set has only one subset: itself. It has no proper subsets.

No. The null set cannot have a proper subset. For any other set, the null set will be a proper subset. There will also be other proper subsets.
You cannot. They are two disjoint subsets of rational numbers.
The set {1, 3} is a proper subset of {1, 2, 3}.The set {a, b, c, d, e} is a proper subset of the set that contains all the letters in the alphabet.All subsets of a given set are proper subsets, except for the set itself. (Every set is a subset of itself, but not a proper subset.) The empty set is a proper subset of any non-empty set.This sounds like a school question. To answer it, first make up any set you like. Then, as examples of proper subsets, make sets that contain some, but not all, of the members of your original set.
If you start with a set with only one element [16187191] then there can be only one proper subset: the empty set.
To find how many proper subsets there are in a set you can use the formula n^2 -n and if you would also like to find all subsets including improper the formula is n^2 -n +1
