What is a Venn diagram?
A Venn diagram is used to visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. In a Venn diagram, sets are represented by shapes usually circles or ovals. The elements of a set are labeled within the circle.
For the given situation,
This information can be represented as Venn diagram as shown below.
Number of students at a college = 60
Number of students studying both French and Spanish = 20
Number of students studying French but not Spanish = 13
Number of students studying Spanish = 43
So, number of students studying French = [tex]13+20[/tex]
⇒ [tex]33[/tex]
Number of students do not studying = [tex]60-43-33+20[/tex]
⇒ [tex]4[/tex]
Hence we can conclude that the given information was completed using Venn diagram.
