Mutually Disjoin Set

Abstract

---

• Also known as Pairwise Disjoint or Non-overlapping*
• Refer to Partition, the elements inside $\{A_1,A_2,A_3,A_4\}$ partition are Mutually Disjoin
• $A$ is called Union of Mutually Disjoint Subsets
• The collection of sets $\{A_1,A_2,A_3,A_4\}$ is said to be a partition of $A$

Disjoin Set

$$A\cap B=\varnothing$$

• Given 2 Set, both don’t have any elements in common
