The expression for determining the number of distinct subsets for a set with n distinct elements is

The expression for determining the number of distinct subsets for a set with n distinct elements is 2^n (2 raise to the power n).

Step-by-step explanation:

The expression for determining the number of distinct subsets for a set with n distinct elements is 2^n (2 raise to the power n).

If a set has 0 elements then it has 1 subset which is a null set (2^0=1)

if a set has 1 element then it has 2 subsets. One is a null set and the other one would be itself (2^1 = 1).

Like wise if a set has 5 elements then it has 32 subsets (2^5 = 32)

Lets solve an example. We have a set A and we have to find the subsets of set A.

A = {1,2,}

2^n = 2^2 = 4

It means that the number of all the possible subsets = 4

{0},{1},{2},{1,2} ...
