Probability is a concept which is used for solving problems that are related to mathematics. Probability is a way to calculate all possible occurring events a/ b when an event has ‘a’ ways to perform and result are obtained in ‘b’ ways. The probability of an event can generally be expressed in the form of range from 0 to 1.

Here we are going to discussing about permutation combination that basically deals with arranging the data values in either ordered form or non order form. Suppose we have different items like d, then the no. of ways to arranging then in a row can be calculated by the factorial d!. In the simple mean we can say that permutation can be consider as a arranging a thing where the ordering of things is considered. In the same aspect combination can be referred as selection of things in which ordering of things doesn’t matter.

In mathematical definition we can say that a permutation is a term which performs the sequencing of numbers by following the finite set order without using any repeated elements. Through this definition we can say that the concept of permutation is similar to the concept of factorial of any number. On the other side the concept combination can be describe as a way of selecting different things without following any specific order. When we simply want to select the total number of possible combination then it can be performed by using multiplication.
