How to Find a Number of Subsets in a set?

The subset can be defined as, if all the elements of A are available in the set B then it is called A subset of B. And it can be expressed as A⊆B. Symbol of the subset is ''⊆''. And also if the elements in A are also included in set B along with some other elements then that set is known as a powerset.

The formula for the subset is 2n.

In this subset, we have two types: 1. proper set and 2. improper set. 

We call a set a proper subset when we have the given set in the subset. And if we see the formula of the proper subset is 2n - 1. 

Improper is the subset which is not a proper subset.

Steps to Calculate Subsets:

Follow the steps or procedure to find the number of subsets in a set.

  • Mainly, note the numbers that were given in the problem.
  • Now, find the number of elements in a set.
  • Then, you need to apply the formula of subset, i.e.,  2n.
  • Finally, substitute the elements in a set as n and find the answer.

Example:

Question: Find the number of subsets of A? If A= { 1,2,3,4}

Solution:

Given, A= { 1,2,3,4}

As the set A contains 4 elements.

Here, n = 4 

Now, Apply the formula of subsets in a set 

=  2n

= 24

= 16.

Therefore, set A has 16 subsets.

Along with this, we have many other maths concepts with the calculator tools on our website onlinecalculator.guide

Frequently Asked Questions on Subset Calculator

1. How subsets can be calculated?

Subsets can be calculated by the formula, i.e.,  2n.

2. What is a proper subset?

Proper subset when we have the given set in the subset.

3. What is the formula for the power set?

The formula of the power set is n[P(A)]  =  2n.
