What is a well defined collection of objects?
Definition: A set is a well-defined collection of distinct objects. The objects of a set are called its elements. If a set has no elements, it is called the empty set and is denoted by ∅.
What is defined set?
A set is a group or collection of objects or numbers, considered as an entity unto itself. Each object or number in a set is called a member or element of the set. Examples include the set of all computers in the world, the set of all apples on a tree, and the set of all irrational numbers between 0 and 1.
What are the ways of representing well defined sets?
Notation: A set is usually denoted by capital letters, i.e. A,B,C,…,X,Y,Z,… etc., and the elements are denoted by small letters, i.e. a,b,c,…,x,y,z,… etc. If A is any set and a is the element of set A, then we write a∈A, read as a belongs to A.
How can Venn diagrams be used in everyday life?
Venn diagrams are commonly associated with education. They are frequently used in mathematics to understand set theory and also used to do various comparisons in the classroom. The power of Venn diagram lie in its simplicity. They are great for comparing things in a visual manner and to quickly identify overlaps.
Who was invented zero?

Who created Venn diagram?
John Venn
Why it is named Venn diagram?
Venn diagrams are named after British logician John Venn. He wrote about them in an 1880 paper entitled “On the Diagrammatic and Mechanical Representation of Propositions and Reasonings” in the Philosophical Magazine and Journal of Science.
What do you put in the inner circle of Venn diagram?
The interior of the circle symbolically represents the elements of the set, while the exterior represents elements that are not members of the set. For instance, in a two-set Venn diagram, one circle may represent the group of all wooden objects, while the other circle may represent the set of all tables.
How do you answer a 3 circle Venn diagram?
Solution:
- For the Venn diagram: Step 1: Draw three overlapping circles to represent the three sets.
- Step 2: Write down the elements in the intersection X ∩ Y ∩ Z.
- Step 3: Write down the remaining elements in the intersections: X ∩ Y, Y ∩ Z and X ∩ Z.
- Step 4: Write down the remaining elements in the respective sets.
How many circles can be in a Venn diagram?
They are often confused with Euler diagrams. While both have circles, Venn diagrams show the whole of a set while Euler diagrams can show parts of a set. Venn diagrams can have unlimited circles, but more than three becomes extremely complicated so you’ll usually see just two or three circles in a Venn diagram drawing.
