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.
Universal set using venn diagram. Given a 1 2 5 6 and b 3 9 what is the relationship between these sets. Venn diagram with universal set and complement of a set all the numbers from the universal set are displayed somewhere within the rectangle or within one or both of the circles. These must be placed outside of the circles within the rectangle as they aren t part of set a or set b but are part of the universal set. In our case the universal set is our ten best friends.
What is a universal set and how it may be represented in a venn diagram set theory. The set of all elements being considered is called the universal set u and is represented by a rectangle.
