- Drawing Venn Diagrams With Sets
Consider the following information:
- A = {1, 2, 3}
- B = {3, 4, 5}
- Universal Set U = {1, 2, 3, 4, 5, 6, 7}
Draw a Venn Diagram describing the 3 sets.

- Understanding How to Use Set Notation
Consider the following information:- Universal set U = {0, 1, 2, 3, 4, 5,...}
- Set N = {all natural numbers}
- Set A = {0}
- Set B = { }
- Consider the following Venn Diagram:
- Universal set U={archery,eating,chess,darts,soccer,basketball,football,volleyball,tennis,badminton}
- Set A={archery,eating,chess,darts}
- Set B={soccer,basketball,football,volleyball}
- Consider the following Venn Diagram:

Notes:
Here are some terms that we need to know for set notations:
Set: A list of objects or numbers.
Element: An object or a number in a set.
n(A): The number of elements in set A.
Subset: A set where all its elements belong to another set.
Universal Set: A set of all elements in a particular context.
Empty Set: A set with no elements.
Disjoint: Two or more sets that do not have any elements in common.
Mutually Exclusive: Two or more events that cannot happen simultaneously.
Finite Set: A set with a finite number of elements.
Infinite Set: A set with an infinite number of elements.
Complement: The list of remaining elements in the universal set that is not in the mentioned set. If B is a set. Then we defined the complement to be B′ or B.
