What is Permutation?
In mathematics, a permutation is an arrangement of a set of objects in a specific order. For example, if the set of objects is {1, 2, 3}, then the possible permutations are:
(1, 2, 3)
(1, 3, 2)
(2, 1, 3)
(2, 3, 1)
(3, 1, 2)
(3, 2, 1)
The number of permutations of a set of n objects is given by n!, which is the product of all the positive integers from 1 to n.
Permutations can be used to describe the possible arrangements of elements in a set, and they have a wide range of applications in various areas of mathematics and other fields.
How to Calculate Number of Permutations of N Different Things taken R at once given One Specific Thing Always Occurs?
Number of Permutations of N Different Things taken R at once given One Specific Thing Always Occurs calculator uses Number of Permutations = (Value of R!)*((Value of N-1)!)/((Value of N-Value of R)!*(Value of R-1)!) to calculate the Number of Permutations, Number of Permutations of N Different Things taken R at once given One Specific Thing Always Occurs formula is defined as the total number of ways in which R different things from the given N things can be arranged such that one specific thing always occurs in the arrangement.
