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 “

Chinese remainder theorem- Once a Chinese riddle asks the following question- Is there a positive integer x such that when x is divided by 3 it yields a remainder 2, when x is divided by 5 it yields a remainder 4, and when x is divided by 7 it yields a remainder 6?
An annuity is a sequence of equal payment or a sequence of regular payment at regular intervals or in other words.
We can lent or borrow money from one entity to another. The price to be paid for the use of a certain amount of money for a certain period of time is known as interest.
The population is the collection or group of observations under study in a survey sampling.The total number of observations in a population is known as population size and it is denoted by N.
The concept of probability distribution gives the idea about the probabilities of any random experiment.

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.
If u and v are functions of the two independent variables x and y , then the determinant, is known as the jacobian of u and v with respect to x and y.
An equated monthly instalment(EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month.
The characteristic equation is the equation which is used to find the Eigenvalues of a matrix. This is also called the characteristic polynomial.
the correction between these n pairs of rank is called the rank correlation in the characteristics A and B for that group of individuals.
