Step 2: Draw a rectangle and label it as per the correlation between the sets.

Step 1: Categorize all the items into sets.

Here are the 4 easy steps to draw a Venn diagram: Since more than three becomes very complicated, we will usually consider only two or three circles in a Venn diagram. Venn diagrams can be drawn with unlimited circles. We can observe the above-explained operations on sets using the figures given below, The region covered by set A, excluding the region that is common to set B, gives the difference of sets A and B. This operation on sets can be represented using a Venn diagram with two circles. It is also referred to as a ‘relative complement’. The difference of sets can be given as, A - B. The region covered in the universal set, excluding the region covered by set A, gives the complement of A. This represents elements that are not present in set A and can be represented using a Venn diagram with a circle. The complement of any set A can be given as A'. The region common to both the circles denotes the intersection of set A and Set B. This operation on set A and B can be represented using a Venn diagram with two intersecting circles. The union of two sets A and B can be given by: A ∪ B =. In set theory, we can perform certain operations on given sets. The number of students that do not prefer a burger.

The number of students that prefer a burger, pizza as well as hotdog. The number of students that prefer both burger and pizza. The number of students that prefer either burger or pizza or both. Let us understand the concept and the usage of the three basic Venn diagram symbols using the image given below. They are listed below as: Venn Diagram SymbolsĮlements that belong to either set A or set B or both the sets.Įlements that belong to both sets A and B. We will learn about the three most commonly used symbols in this section.

There are more than 30 Venn diagram symbols. Here N ⊂ I, because all-natural numbers are integers.It is read as A is a subset of B or A subset B. This relationship is symbolically represented as A ⊆ B. Also, all the elements of A are elements of set B. Circle A is contained entirely within circle B. Let us consider the examples of two sets A and B in the below-given figure. A subset is actually a set that is contained within another set. All the numbers between 1-10, that are not even, will be placed outside the circle and within the rectangle as shown above.A is the set of even numbers 1-10, which is the subset of the universal set U and it is placed inside the rectangle.U is the universal set with all the numbers 1-10, enclosed within the rectangle.Every set is the subset of the universal set U.All the other sets are represented by circles or closed figures within this larger rectangle.A large rectangle is used to represent the universal set and it is usually denoted by the symbol E or sometimes U.Whenever we use a set, it is easier to first consider a larger set called a universal set that contains all of the elements in all of the sets that are being considered.

Let us understand the following terms and concepts related to Venn Diagram, to understand it better. The intersecting part shows that 10 and 20 are both even numbers and also multiples of 5 between 1 to 25.One set contains even numbers from 1 to 25 and the other set contains the numbers in the 5x table from 1 to 25.Here is the Venn diagram that shows the correlation between the following set of numbers. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets. A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets.
