What Is Discrete Mathematics? Answer : Discrete Mathematics is a branch of mathematics involving discrete elements that uses algebra and arithmetic. It is increasingly being applied in the practical fields of mathematics and computer science. It is a very good tool for improving reasoning and problem-solving capabilities. Question 2.

It is characterized by the fact that between any two numbers, there are almost always an infinite set of numbers.

For example, a function in continuous mathematics can be plotted in a smooth curve without breaks. For example, if we have a finite set of objects, the function can be defined as a list of ordered pairs having these objects, and can be presented as a complete list of those pairs. Question 3. Answer : 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.

Question 4. Roster or Tabular Form: The set is represented by listing all the elements comprising it. The elements are enclosed within braces and separated by commas.

Set Builder Notation: The set is defined by specifying a property that elements of the set have in common. Question 5.Antisymmetric Bisymmetric Anti reflexive.

The number of regions corresponds to the cyclomatic complexity. Share to:. A graph G is called a What is the probability of choosing correctly an unknown integer between 0 and 9 with 3 chances? In an undirected graph the number of nodes with odd degree must be. A graph is a collection of. Vertices and edges. An undirected graph possesses an eulerian circuit if and only if it is connected and its vertices are.

How many relations are there on a set with n elements that are symmetric and a set with n elements that are reflexive and symmetric?

The number of colours required to properly colour the vertices of every planer graph is. In how many ways can a president and vice president be chosen from a set of 30 candidates? Consider an undirected random graph of eight vertices. What is the expected number of unordered cycles of length three?

A minimal spanning tree of a graph G is. All of above. The number of leaf nodes in a complete binary tree of depth d is. A partial ordered relation is transitive, reflexive and. In how many ways can a hungry student choose 3 toppings for his prize from a list of 10 delicious possibilities?

A graph with n vertices will definitely have a parallel edge or self loop if the total number of edges are. A vertex of a graph is called even or odd depending upon. Total number of edges in a graph is even or odd. Total number of vertices in a graph is even or odd. Its degree is even or odd. In any undirected graph the sum of degrees of all the nodes. Are twice the number of edges. A graph with one vertex and no edges is.

Length of the walk of a graph is. The number of edges in walk W.The set of positive integers excluding zero with addition operation is a semigroup. A monoid is a semigroup with an identity element. An identity element is also called a unit element. The set of positive integers excluding zero with multiplication operation is a monoid.

Here identity element is 1. A group is a monoid with an inverse element. So, a group holds four properties simultaneously - i Closure, ii Associative, iii Identity element, iv Inverse element. The order of a group G is the number of elements in G and the order of an element in a group is the least positive integer n such that an is the identity element of that group G. As all the matrices are non-singular they all have inverse elements which are also nonsingular matrices.

Hence, inverse property also holds. So, a group holds five properties simultaneously - i Closure, ii Associative, iii Identity element, iv Inverse element, v Commutative. The set of positive integers including zero with addition operation is an abelian group. Here, identity element is 1. A cyclic group is a group that can be generated by a single element. Every element of a cyclic group is a power of some specific element which is called a generator.

Hence, it is a cyclic group. The rational numbers under addition is not cyclic but is abelian. A subgroup of a cyclic group is cyclic and a abelian subgroup is also abelian. A partially ordered set consists of a set with a binary relation which is reflexive, antisymmetric and transitive. The Hasse diagram of a poset is the directed graph whose vertices are the element of that poset and the arcs covers the pairs x, y in the poset.

A Linearly ordered set or Total ordered set is a partial order set in which every pair of element is comparable. Trichotomy law defines this total ordered set. Hence, it is not a total ordered set.

A lattice L becomes a complemented lattice if it is a bounded lattice and if every element in the lattice has a complement. If a lattice satisfies the following two distribute properties, it is called a distributive lattice. Discrete Mathematics - Group Theory Advertisements.
