Venn diagram formula for 2 sets. In cat and other mba entrance exams questions asked from this topic involve 2 or 3 variable only. Union of 2 sets. Do you see that alex casey drew and hunter are in the soccer set. The simplest and most typical venn diagram depicts two overlapping circles.
The usual depiction makes use of a rectangle as the universal set and circles for the sets under consideration. It is a pictorial representation of logical or mathematical sets that are drawn in an enclosing rectangle rectangle representing the universal set as circles. Problem solving using venn diagram is a widely used approach in many areas such as statistics data science business set theory math logic and etc. It has been perhaps 3 years since i have done venn diagram so i have gotten really rusty at this.
A venn diagram consists of multiple overlapping closed curves usually circles each representing a set. I have such a hard time visualising these diagrams and knowing what to subtract from intersection etc. The best way to explain how the venn diagram works and what its formulas show is to give 2 or 3 circles venn diagram examples and problems with solutions. A venn diagram or set diagram is a diagram that shows all possibilities of overlap and non overlap of two or more sets.
The usual picture makes use of a rectangle as the universal set and circles for the sets under consideration. Venn diagrams of 2 sets if the two given objects are called a b. And that casey drew and jade are in the tennis set. The sum of a b here is known as a union b and is symbolically represented as a b.
I understand venn diagram equations of 2 sets. Venn diagram representing mathematical or logical sets pictorially as circles or closed curves within a rectangle. I don t understand in the equation for 3 sets why in the end they add the intersection of 3 sets. Enter an expression like a union b intersect complement c to describe a combination of two or three sets and get the notation and venn diagram.
