Sets and subsets may be represented using venn diagrams.
Math universal set venn diagram. This relationship is shown in the venn diagram below. These are diagrams that make use of geometric shapes to show relationships between sets. What is a universal set and how it may be represented in a venn diagram set theory. U alex blair casey drew erin francis glen hunter ira jade we can show the universal set in a venn diagram by putting a box around the whole thing.
Readings for session 5 continued universal set and venn diagrams. A and b have no elements in common. In previous lessons we learned that a set is a group of objects and that venn diagrams can be used to illustrate both set relationships and logical relationships. The following diagrams show the set operations and venn diagrams for complement of a set disjoint sets subsets intersection and union of sets.
A universal set sometimes called the universe is the set of all items under consideration for a particular problem or situation. In our case the universal set is our ten best friends. Note that although there are no elements shown inside. Venn diagram 1 provides a concise introduction into the concept of the venn diagram and its use in determining members of sets in mathematics.

The complement of the set a is denoted as a so a 10 14 18 22 if b is a subset of a universal set then b is represented in a venn diagram as follows. How to fill in a venn diagram when the universal set is included. The set of all elements being considered is called the universal set u and is represented by a rectangle.
Universal set venn diagrams absolute complement intersection union and complement of sets examples with step by step solutions. Given a 1 2 5 6 and b 3 9 what is the relationship between these sets. Let the universal set u be all the elements in sets a b c and d. The universal set contains everything we are interested in at that particular time.
A venn diagram begins with a box called our universal set which is denoted by the symbol ε epsilon. We will let set u unless otherwise defined represent the universe in a given problem or situation. Now you can see all your ten best friends neatly sorted into what sport they play or not. Now let s find the elements which belong to the universal set but not in the set a 10 14 18 22 this is the complement of the set a.
