The number of subjects will depend on what the elements of the set are. The number of subsets is 2a.

That means, figure out how many different subsets a set has. In general, if a set has n elements, it has 2n different subsets.

A set with 50 elements has 250 subsets.

A set with N elements has 2N subsets.

A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.

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)

An element doesn't have subsets. Sets can have subsets.

A set with 9 elements has 2^9 = 512 subsets.

A set with 50 elements has 250 subsets.

A set with N elements has 2N subsets.

Hi Suppose, I found that number of subsets of set S having n elements can be found by using formula 2^n, where n is number of elements of S. Let S(n) represents number of subsets of set S having n elements. S(n) = 2^n S(n+1) = 2^(n+1)

If the universal set contains N elements then it has 2N subsets.
