Sets Intersection

MinilessonsGraphic OrganizersInteractive Notebooks.This formula is particularly useful when finding the probability of an event directly is difficult. Although it is tedious to list them all, it is not difficult to count them.

Think of using a tree diagram to do so. There are two choices for the first toss. The intersection corresponds to the shaded lens-shaped region that lies within both ovals.

This gives the following rule:. The union corresponds to the shaded region.

Unions And Intersection

A two-child family is selected at random. The next example, in which we compute the probability of a union both by counting and by using the formula, shows why the last term in the formula is needed.

As was the case with tossing two identical coins, actual experience dictates that for the sample space to have equally likely outcomes we should list outcomes as if we could distinguish the two dice. We could imagine that one of them is red and the other is green. Then any outcome can be labeled as a pair of numbers as in the following display, where the first number in the pair is the number of dots on the top face of the green die and the second number in the pair is the number of dots on the top face of the red die.

A tutoring service specializes in preparing adults for high school equivalence tests. What is the percentage of students who need help in either mathematics or English? Imagine selecting a student at random, that is, in such a way that every student has the same chance of being selected. Thus the Additive Rule of Probability gives:. The percentage that need help in both subjects must be subtracted off, else the people needing help in both are counted twice, once for needing help in mathematics and once again for needing help in English.

The results are shown in the following two-way classification table:. Similarly for the other two rows. A volunteer is selected at random, meaning that each one has an equal chance of being chosen.

Find the probability that:. When information is presented in a two-way classification table it is typically convenient to adjoin to the table the row and column totals, to produce a new table like this:.

To learn how to use special formulas for the probability of an event that is expressed in terms of one or more other events. Suppose the die is fair. Find the probability that the number rolled is both even and greater than two. Now find the probability that the number rolled is both even and greater than two. Find the probabilities of the following events: both dice show a four at least one die shows a four Solution : As was the case with tossing two identical coins, actual experience dictates that for the sample space to have equally likely outcomes we should list outcomes as if we could distinguish the two dice.

This is the computation from part 1, of course. Solution : Imagine selecting a student at random, that is, in such a way that every student has the same chance of being selected. Key Takeaway The probability of an event that is a complement or union of events of known probability can be computed using formulas.By Mary Jane Sterling. Sets of elements can be combined or changed by using set operations. Much like addition or subtraction of real numbers, set operations are strictly defined to do something to the sets involved.

The set operations are union, intersection, and complement:. The union of two sets A and B asks for all the elements in sets A and B — all of them together without repeating any elements that they share.

[Discrete Mathematics] Set Operations

The intersection of the two sets A and B asks for all the elements that A and B have in common. If the two sets have nothing in common, then your answer is the empty set or null set.

The universal set is everything under consideration at the time. The union of A and B consists of all the elements in A and B both, so. The intersection of A and B consists of all the elements the two sets share, so.

The intersection of B and C is all the elements that the two sets share, but the two sets have nothing in common, so. The complement is everything except the 1 and 3 in the intersection. You write the intersection — what the two results have in common — as. The union of A and B contains everything from A — all the even numbers from 0 to 20 — and everything from B — the multiples of 5 from 0 to Essentially, you just list the even numbers and insert the 5 and 15 from set B.

The 0 and 10 and 20 are already accounted for.Why don't fictional characters say "goodbye" when they hang up a phone? If we can't tunnel through the Earth, how do we know what's at its center?

But, there is no such thing as a "union intersection set", as required for the answer to the question. The concept of closure: If A and B are sets the intersection of sets is a set. Then if the intersection of two sets is a set and that set could be empty but still a set. The same for union, a set A union set Null is a set by closure,and is the set A.

Asked in Math and Arithmetic, Algebra Is there any case when union and intersection are same in sets? Asked in Math and Arithmetic What is set operation in math? The main set operations are: union, intersection and complement.

Asked in Calculus How will you write using the venn diagram the union of set a and the intersection of set b and set c ? The union of A with an empty set is set A. Asked in Math and Arithmetic, Algebra What are set operations in math?

The basic operations are union, intersection and complement. Asked in Math and Arithmetic, Algebra What are operations of sets? The complement of the set is also a basic operation.This instructional unit on sets provide a step-by-step introduction to sets and set theory.

We define a set by listing or describing its elements. Basic Set Notation Basic notation is used to indicate whether or not an element belongs to a set. Connections are made to language arts, science and social studies. Types of Sets Students learn about finite and infinite sets, as well as the empty or null set. Roster notation is used. Connections are made to art, science, and language arts.

Set Equality Students learn how to determine if two sets are equal. The order in which the elements appear in the set is not important. Real-world connections are made with sets. Venn Diagrams Venn diagrams are used to represent sets pictorially, and to show relationships and logical relationships between sets. Intersection and union of overlapping sets are introduced. Subsets Venn diagrams are used to show subsets, with one set contained within the other.

The distinction between subsets and proper subsets is made. The relationship between equal sets and subsets is presented, as well as how to determine the number of subsets a given set can have. Universal Set The Universal set is presented as the set of all elements under consideration. Complete Venn diagrams are used to represent sets which are disjoint, overlapping, or one contained within another. Real-world connections are made. Set-Builder Notation Set-builder notation is introduced as a shorthand for writing sets, including formulas, notation and restrictions.

Common types of numbers are defined, including natural numbers, integers, and real and imaginary numbers. Students are shown why they need set-builder notation. Complement The complement of a set is defined and shown through numerous examples. Set-builder notation and Venn diagrams are included.

Connections are made to the real world. Intersection The intersection of two sets is defined and shown through examples with Venn diagrams.

Examples include overlapping sets, disjoint sets, and subsets.Parents, teachers and educators can now present the knowledge using these vividly presented short videos.

For example, you and a new roommate decide to have a house party, and you both invite your circle of friends.

At this party, two sets are being combined, though it might turn out that there are some friends that were in both sets. The union of two sets contains all the elements contained in either set or both sets.

The intersection of two sets contains only the elements that are in both sets. The complement of a set A contains everything that is not in the set A. A universal set is a set that contains all the elements we are interested in. This would have to be defined by the context.

Notice that in the example above, it would be hard to just ask for A csince everything from the color fuchsia to puppies and peanut butter are included in the complement of the set. For this reason, complements are usually only used with intersections, or when we have a universal set in place.

Grouping symbols can be used like they are with arithmetic — to force an order of operations. To visualize the interaction of sets, John Venn in thought to use overlapping circles, building on a similar idea used by Leonhard Euler in the 18th century.

These illustrations now called Venn Diagrams. A Venn diagram represents each set by a circle, usually drawn inside of a containing box representing the universal set.

Overlapping areas indicate elements common to both sets. Ac will contain all elements not in the set A. The elements in the outlined set are in sets H and Fbut are not in set W. Skip to main content. Module 6: Set Theory and Logic.

Union, Intersection, and Complement Learning Outcomes Describe memberships of sets, including the empty set, using proper notation, and decide whether given items are members and determine the cardinality of a given set. Describe the relations between sets regarding membership, equality, subset, and proper subset, using proper notation. Perform the operations of union, intersection, complement, and difference on sets using proper notation.

Be able to draw and interpret Venn diagrams of set relations and operations and use Venn diagrams to solve problems. Recognize when set theory is applicable to real-life situations, solve real-life problems, and communicate real-life problems and solutions to others.

Union, Intersection, and Complement The union of two sets contains all the elements contained in either set or both sets. Example If we were discussing searching for books, the universal set might be all the books in the library.

If we were grouping your Facebook friends, the universal set would be all your Facebook friends. If you were working with sets of numbers, the universal set might be all whole numbers, all integers, or all real numbers. Try It. Venn Diagram A Venn diagram represents each set by a circle, usually drawn inside of a containing box representing the universal set.
