The assignment was about knowing different types of sets and their properties which helps us in relating a collection, aggregate or class of objects. The assignment necessitated understanding the concepts of permutation ( arrangement of things in different ways) and combinations (Selection of objects in different ways). It also involved some statistical analysis like finding the odds in favor or against the occurrence of a particular event and find number of ways in which a particular task can be accomplished.
