If there are certain pets that fit both the categories, then place them at the intersection of sets, where the circles overlap. Step 4: Place all the pets in the relevant circles.So, let us draw two circles and make sure the circles overlap. There are two categories in the sample question: outdoor pets and indoor pets. Step 3: Draw the circles according to the number of categories you have.Step 2: Draw a rectangle and label it as per the correlation between the two sets. Both categories (outdoor and indoor): Rabbits and Fish. Outdoor pets: Horses, Tortoises, and Goats. Step 1: Categorize all the items into sets (Here, its pets): Indoor pets: Cats, Hamsters, and, Parrots.Step 4: Place all the items in the relevant circles.Įxample: Let us draw a Venn diagram to show categories of outdoor and indoor for the following pets: Parrots, Hamsters, Cats, Rabbits, Fish, Goats, Tortoises, Horses.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.
