A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.
The commonly-used diagram for the Borromean rings consists of three equal circles centered at the points of an equilateral triangle, close enough together that their interiors have a common intersection (such as in a Venn diagram or the three circles used to define the Reuleaux triangle).
The three Venn diagrams in the figure below represent respectively conjunction x ∧ y, disjunction x ∨ y, and complement ¬x. Figure 2. Venn diagrams for conjunction, disjunction, and complement. For conjunction, the region inside both circles is shaded to indicate that x ∧ y is 1 when both variables are 1.
A Venn diagram is a representation of mathematical sets: a mathematical diagram representing sets as circles, with their relationships to each other expressed through their overlapping positions, so that all possible relationships between the sets are shown. [4]
E.g. row AB corresponds to the 2-circle, and row ABC to the 3-circle Venn diagram shown above. (As in the Venn diagrams, white is false, and red is true.) The truth table of A ⊕ B {\\displaystyle A\\oplus B} shows that it outputs true whenever the inputs differ:
The third circle identifies something people want. For Chan, he knew there was a huge problem with financial literacy in the U.S. The sweet spot in the model is where all three circles overlap.
The intersection of two sets and , represented by circles. is in red. Type: Set operation: Field: Set theory ... The intersection of the sets {1, 2, 3} and {2, 3, 4 ...
Information diagrams have also been applied to specific problems such as for displaying the information theoretic similarity between sets of ontological terms.
