Pigeonhole principle-If n pigeonholes are occupied by n + 1 or more pigeons, then at least one pigeonhole is occupied by more than one pigeon.

The K-Map is used to simplify the Boolean Functions in a very easy way. The K-Map was introduced by Karnaugh. 

Errors may rise from different sources and are classified as gross error, systematic error and random errors.

Output Devices are the devices that are used to show the results or details.

A tree data structure is a non-linear data structure since it does not store data in a sequential order.

A flowchart is a diagrammatic description of any process or workflow that uses symbols to express it in a systematic and sequential manner.

The Java AWT API is a set of classes and methods for developing and managing GUI applications.

These standards mainly represent the units of measurements which are close to the possible accuracy with help of present day technological.

Let X and Y are two sets. A relation f from X to Y is said to be a function if for every x ∈ X there is a unique element y ∈ Y, such that (x, y) ∈ X

Introduction: In order to understand the concept of relations, let’s consider the following example:

The concept of sets is widely used in mathematics as well as in other fields such as engineering, computer sciences etc.

The exponential distribution is a continuous probability distribution and it is a widely used distribution in various fields such as engineering, research, data sciences etc.

For drawing less than cumulative frequency polygon or curve (or less than ogive), first of all the cumulative frequencies are plotted against the values (upper limits of the class intervals) up to which they correspond and then we simply join the points by line segments, curve thus obtained is known as less than ogive.

Integration is the reverse process of differentiation. It is also called anti-differentiation.

The consumer price index measures the amount of money which consumers of a particular class have to pay to get a basket of goods & services at a particular point of time in comparison to what they paid for the same in the base period.

Let X and Y are two sets. A relation f from X to Y is said to be a function if for every x ∈ X there is a unique element y ∈ Y, such that (x, y) ∈ X

Shares and mutual funds-Share is the smallest unit of the capital of a company. In other words, A unit of ownership, that represents an equal proportion of a company’s capital is called as shares.

Before studying about permutation and combination, we will have to know about factorial.The product of the positive integers from 1 to n is denoted by n! And we read it as “factorial “

When the changes in one variable are associated or followed by change in the other, we say that there is a correlation between the two. Such data connecting two variables is called a bivariate population.

A number system is a way of writing any number. It can be represented by using any symbols or digits. It provides distinctive representation.
