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

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.

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.

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

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

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

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.

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 “

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
