A \cup B = \{x|x \in A\text{ and }x\in B\} If A and B are sets, we define their intersection as the set consisting of all elements that belong to both A and B and denote it by A \cup B. Two sets that have no common elements are called disjoint sets. A-B=\{x|x\...
Discrete Mathematics - Sets - German mathematician G. Cantor introduced the concept of sets. He had defined a set as a collection of definite and distinguishable objects selected by the means of certain rules or description.
