## What are proper subsets?

What are Proper Subsets? Set A is considered to be a proper subset of Set B if Set B contains at least one element that is not present in Set A. Example: If set A has elements as {12, 24} and set B has elements as {12, 24, 36}, then set A is the proper subset of B because 36 is not present in the set A.

## What is the symbol for proper subset?

Proper Subset Symbol. A proper subset is denoted by ⊂ and is read as ‘is a proper subset of’. Using this symbol, we can express a proper subset for set A and set B as; A ⊂ B. Proper Subset Formula. If we have to pick n number of elements from a set containing N number of elements, it can be done in NCn number of ways.

What is the difference between a subset and superset?

If a set A is a collection of even number and set B consists of {2,4,6}, then B is said to be a subset of A, denoted by B⊆A and A is the superset of B. Learn Sets Subset And Superset to understand the difference. The elements of sets could be anything such as a group of real numbers, variables, constants, whole numbers, etc.

### How many subsets contain 3 elements from the set S?

Therefore, the number of possible subsets containing 3 elements from the set S = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 } is 120. Example 2: Given any two real-life examples on the subset. Solution: We can find a variety of examples of subsets in everyday life such as:
