Set operations venn diagram examples. To visualize set operations we will use venn diagrams in a venn diagram a rectangle shows the universal set and all other sets are. A is the set of multiples of 3. A a b b a b c a b. Venn diagrams a set can be visualized using venn diagrams.
A set is a collection of things. C is the set of odd numbers 2. Browse more topics under sets. Sets are treated as mathematical objects.
Sets and venn diagrams sets. 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. Venn diagrams most of the relationships between sets can be represented by means of diagrams which are known asvenn diagrams. The universal set is represented usually by a rectangle and its subsets by circles.
Similarly to numbers we can perform certain mathematical operations on sets below we consider the principal operations involving the intersection union difference symmetric difference and the complement of sets. A venn diagram is also known as a primary diagram set diagram or logic diagram. Create a venn diagram to show the relationship among the sets. Alternate way to define a is a subset of b.
The difference subtraction is defined as follows. We use a b to indicate a is a subset of b. For example the items you wear is a set. Given the following venn diagram determine each of the following set.
B is the set of primes. Let the universal set u represent the set of all us corporations in 2001. Venn diagrams are named after the english logician john venn 1834 1883. 2 3 venn diagrams and set operations 2nd hour started notebook 7 september 04 2015 example 2.

U is the set of whole numbers from 1 to 15. Fig 1 7 the shaded area shows the set bar a a c. These include hat shirt jacket pants and so on. These diagrams consist of rectangles and closed curves usually circles.
U is the set of whole numbers from 1 to 15. V a b c u a b c cs 441 discrete mathematics for cs m. In figure 1 7 bar a is shown by the shaded area using a venn diagram. You write sets inside curly brackets like this.
Given the following venn diagram determine each of the following sets. A set a is said to be a subset of b if and only if every element of a is also an element of b. A is the set of multiples of 3. Hauskrecht a subset definition.
They are extensively used to teach set theory.
