8 subsets
If the universal set contains N elements then it has 2N 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)
If you have a set of 6 elements, you can make a total of 26 different subsets - including the empty set and the set itself.
give the total subset of set with 9 elements
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.
6
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
An element doesn't have subsets. Sets can have subsets.

Only a set can have subsets, a number cannot have subsets.
5 subsets of 4 and of 1, 10 subsets of 3 and of 2 adds up to 30.
That means, figure out how many different subsets a set has. In general, if a set has n elements, it has 2n different subsets.
If the universal set contains N elements then it has 2N subsets.
512 subsets
Two. The set {x} has the subsets {} and {x}.
