About Discrete Mathematics

This le contains an English version of exercises in the course of Discrete mathematics. Most of the problems were prepared by Michael Kubesa, Tereza Kova rov a, and Petr Kov a r. From the solution of the previous example we can obsereve, that the ordered pair e2 is not in A B, but it is in B A. Therefore, in general A B6 B A. In

Introduction to Discrete Mathematics The field of mathematics known as discrete mathematics is concerned with the study of discrete mathematical structure. There are two different types of data discrete and continuous. Instead of studying continuous data, discrete mathematics examines discrete data. Finite mathematics is another name for it.

taking a discrete mathematics course make up a set. In addition, those currently enrolled students, who are taking a course in discrete mathematics form a set that can be obtained by taking the elements common to the first two collections. Definition A set is an unordered collection of objects, called elements or members of the set.

Discrete Mathematics is a field of mathematics concerned with the study of discrete mathematical structures. It examines discrete data rather than continuous data. It includes important concepts such as logic, sequences and series, set theory, graph theory, permutation, induction, combinations, etc.

2.5 points Consider a scenario where a student is represented by S, and the fol- lowing predicates are given CS Returns true if the student studies computer science. MS Returns true if the student studies mathematics. GS 1,S 2 Returns true if student S 1 has a higher grade than student S 2. Express the following statements using formal mathematical logic.

Sample Problems in Discrete Mathematics This handout lists some sample problems that you should be able to solve as a pre-requisite to Design and Analysis of Algorithms. Try to solve all of them. You should also read Chapters 2 and 3 of the textbook, and look at the Exercises at the end of these chapters.

The set of solutions is the empty set. Indeed, suppose x 6a 2 9b 3 for some integers a and b. Then 3 2a 3b 6a 9b 3 2 1. Hence three times an integer equals 1. This is impossible, so there are no solutions. 7. Let E be the event that x1 1, and F be the event that x1 1
