2n - 1
If the set is of finite order, that is, it has a finite number of elements, n, then the number of subsets is 2n.
If the set has n elements, the number of subsets (the power set) has 2n members.
The number 8 is not a set and so cannot have any subsets. The set consisting of the number 8 is a set and, since it has only one element in it, it has two subsets: itself and the null set.
512 subsets
meaning of proper subsets
A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.

The subsets of a fraction refer to the individual components that make up the fraction. For example, the subsets of the fraction 3/4 would be the numerator (3) and the denominator (4). In set theory, a subset is a set that contains elements of another set, so in the context of fractions, the subsets are the parts that form the fraction.
The empty set has only one subset: itself. It has no proper subsets.
To get the number of subsets of size less than 2:Total number of subsets of a set of size N is 2NTotal number of subsets of size 1 is 100Total number of subsets of size 0 is 1Total number of subsets of size 2 is 100*99/2 = 4950Sum up: 100 + 1 + 4950 = 5051Subtract this from total subsets: 2100 - 5051 (Answer)
The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.

Only a set can have subsets, a number cannot have subsets.
If the set is of finite order, that is, it has a finite number of elements, n, then the number of subsets is 2n.
If the set has n elements, the number of subsets (the power set) has 2n members.
The null set is a proper subset of any non-empty set.
