Find the no. of +ve integral solution of XYZ = 21600
A permutation is a mathematical concept that refers to the arrangement of a set of objects in a specific order. It is often denoted using the notation nPr, where n represents the total number of objects and r represents the number of objects being arranged.
Permutation and combination are both ways of selecting and arranging objects, but they differ in terms of the order of arrangement. In permutation, the order of objects is important, while in combination, the order is not important.
The formula for calculating permutations is n!/(n-r)!, where n represents the total number of objects and r represents the number of objects being arranged. This formula is also known as the permutation formula or the factorial formula.
Permutation has many real-life applications, such as in the arrangement of letters in a word, the shuffling of playing cards, and the formation of teams in a sports tournament. It is also used in coding and cryptography to generate unique codes and passwords.
To solve permutation problems, you can follow the steps of identifying the total number of objects, determining the number of objects being arranged, and plugging the values into the permutation formula. It is also helpful to practice with sample problems and work systematically to avoid mistakes.
