Relations between sets: Disjoint sets: Two sets A and B are said to be disjoint if they have no common element. e.g. A = and B= Here, A and B are disjoint sets because they have no common elements. In Venn-diagram,.
Scene 6 (57s)
Overlapping or intersecting sets: Two sets A and B are said to be overlapping sets if they have common element. e.g. A = and B = Here, A and B are overlapping sets because they have a common element b. In a Venn-diagram,.

Subsets: A set A is said to be a subset of another set B if every element of A is also an element of set B. e.g. A = and B = Here, A is subset B because every element of set A is also an element of set B. In Venn-diagram,.
