### What is the total number of proper subsets of the set 1 2 3 100?

Answer: In general, number of subsets of a set having ‘n’ elements is 2^n. Out of these, null set and the set itself are not proper subsets. Thus number of subsets of such a set is (2^n)-2, thus number of proper subsets of the given set are (2^3)-2= 8-2=6.

How many subsets are in a set?

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.

What is the power set of the 1 2 set?
