## Discrete Mathematics - Sets

German mathematician G. Cantor introduced the concept of sets. He had defined a set as a collection of definite and distinguishable objects selected by the means of certain rules or description. Set theory forms the basis of several other fields of study like counting theory, relations, graph theory and finite state machines. In this chapter, we will cover the different aspects of Set Theory. A set is an unordered collection of different elements. A set can be written explicitly by listing its elements using set bracket.

If the order of the elements is changed or any element of a set is repeated, it does not make any changes in the set. The set is represented by listing all the elements comprising it. The elements are enclosed within braces and separated by commas. The set is defined by specifying a property that elements of the set have in common. The number is also referred as the cardinal number.

It occurs when the number of elements in X is exactly equal to the number of elements in Y. It occurs when number of elements in X is less than or equal to that of Y. It occurs when number of elements in X is less than that of Y. The sets X and Y are commonly referred as equivalent sets.

Sets can be classified into many types. Some of which are finite, infinite, subset, universal, proper, singleton set, etc. Here set Y is a subset of set X as all the elements of set Y is in set X. It is a collection of all elements in a particular context or application. All the sets in that context or application are essentially subsets of this universal set.

An empty set contains no elements. As the number of elements in an empty set is finite, empty set is a finite set. The cardinality of empty set or null set is zero. Singleton set or unit set contains only one element. Two sets A and B are called disjoint sets if they do not have even one element in common. Venn diagram, invented in by John Venn, is a schematic diagram that shows all possible logical relations between different mathematical sets.

The common element occurs only once. Power set of a set S is the set of all subsets of S including the empty set. Bell numbers give the count of the number of ways to partition a set.

Sets are used extensively in counting problems, and for such applications we need to discuss the sizes of sets. Definition: Let S be a set. If there are exactly n.

## Discrete Mathematics Exam Questions And Answers Pdf

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics — such as integers , graphs , and statements in logic  — do not vary smoothly in this way, but have distinct, separated values. Discrete objects can often be enumerated by integers. More formally, discrete mathematics has been characterized as the branch of mathematics dealing with countable sets  finite sets or sets with the same cardinality as the natural numbers. ### Discrete mathematics

Please make sure the PDF you submit is redable see advice on course site. Remember to follow the course pledge you read and signed at the beginning of the semester. For this assignment, you may discuss the problems and work on solutions with anyone you want including other students in this class , but you must write your own solutions and understand and be able to explain all work you submit on your own. To confirm your own understanding, after discussing the problems with others, you should attempt to write your solutions on your own without consulting any notes from group work sessions. If you get stuck, you may visit notes from the group work sessions, but should make sure you understand things well enough to produce it on your own. Since the staff and students benefit from being able to both reuse problems from previous years, and from being able to provide detailed solutions to students, it is important that students do not abuse these materials even if it is easy to find them.

Set theory has its own notations and symbols that can seem unusual for many. In this tutorial, we look at some solved examples to understand how set theory works and the kind of problems it can be used to solve. Question: In a class of students, 35 like science and 45 like math. How many like either of them and how many like neither? As it is said, one picture is worth a thousand words. One Venn diagram can help solve the problem faster and save time.

This booklet consists of problem sets for a typical undergraduate discrete mathematics own, without the temptation of a solutions manual! These problems.

Solved basic word problems on sets:. Different types on word problems on sets:. In a group of 60 people, 27 like cold drinks and 42 like hot drinks and each person likes at least one of the two drinks. How many like both coffee and tea?

Танкадо - мастер высокого класса, он никогда не оставил бы висячие строки, тем более в таком количестве.

Она уже готова была выскочить из комнаты, когда Стратмор наконец повернул рубильник и вырубил электропитание. В одно мгновение в шифровалке установилась полная тишина. Сирены захлебнулись, мониторы Третьего узла погасли. Тело Грега Хейла растворилось в темноте, и Сьюзан, инстинктивно поджав ноги, прикрылась пиджаком Стратмора. В шифровалке никогда еще не было так тихо, здесь всегда слышался гул генераторов.

Хейл остановился: - Диагностика? - В голосе его слышалось недоверие.  - Ты тратишь на это субботу, вместо того чтобы развлекаться с профессором. - Его зовут Дэвид.

ГЛАВА 32 Дэвид Беккер остановился в коридоре у номера 301. Он знал, что где-то за этой витиеватой резной дверью находится кольцо. Вопрос национальной безопасности. За дверью послышалось движение, раздались голоса. Он постучал.

Хейл сдавил горло Сьюзан немного сильнее, и она вскрикнула от боли. - Ну что, вы решили. Я ее убиваю. Стратмор мгновенно взвесил все варианты.
