Number Sets Venn Diagram
First we will use a venn diagram to find the intersection of two sets.
Number sets venn diagram. Draw and label a venn diagram to show the intersection of sets x and y. A venn diagram also called primary diagram set diagram or logic diagram is a diagram that shows all possible logical relations between a finite collection of different sets these diagrams depict elements as points in the plane and sets as regions inside closed curves. N a b n a n b n a b where. A venn diagram consists of multiple overlapping closed curves usually circles each representing a set.
Y number of elements that belong to set b only. From the above venn diagram it is quite clear that. X the number of items that belong to set a y the number of items that belong to set b z the number of items that belong to set a and b both. List out the elements of p.
A venn diagram usually looks like the on underneath. Let us say the third set is volleyball which drew glen and jade play. Label it p put the elements in p. The intersection of two sets is all the elements they have in common.
They allow you to visually represent sets. Venn diagram for 2 sets. Let s say that our universe contains the numbers 1 2 3 and 4 so u 1 2 3 4. The following examples should help you understand the notation terminology and concepts relating venn diagrams and set notation.
Now let s move forward and think about venn diagrams with 3 circles. To be able to list the numbers in any of the sets it is important we understand a little bit more about a venn diagram. Venn diagrams can be used to express the logical in the mathematical sense relationships between various sets. We need to find the elements that are common in both sets.
This venn diagram contains the sets a b and c and which include the numbers from 1 to 9. It consist of overlapping circle s in a box. N a x z n b y z n a b z n a b x y z. Let x 1 2 3 and let y 3 4 5.
P 16 18 20 22 24 between does not include 15 and 25 draw a circle or oval. Draw and label a venn diagram to represent the set p and indicate all the elements of set p in the venn diagram. You can also use venn diagrams for 3 sets. Z number of elements that belong to set a and b both a b w number of elements that belong to none of the sets a or b.
Volleyball drew glen jade. The venn diagram shows some information about sets a and b.
