Kerala Plus One Maths Notes Chapter 7 Permutation and Combinations<\/h2>\n

I. Fundamental Principle of Counting<\/span>
\nIf an event can occur in \u2018m’ different ways, following which another event can occur in \u2018n\u2019 different ways, then the total number of occurrences of the events in the given order is m \u00d7 n.<\/p>\n

II. Permutation<\/span>
\nA permutation is the arrangement of some or all of a number of different objects.<\/p>\n

Factorial notation: The notation n! represents the product of first n natural numbers,
\nie; n! = n(n – 1 )(n – 2) ….. 3.2.1
\n1. 1! = 1
\n2. 0! = 1<\/p>\n

The number of permutation of \u2018n\u2019 different objects taken ‘r’ at a time, where the objects do not repeat is n(n – 1)(n – 2)……(n – r + 1) which is denoted by n<\/sup>Pr<\/sub>.
\n\"Plus
\nThe number of permutation of \u2018n\u2019 different objects taken ‘r’ at a time, where repetition is allowed is nr<\/sup>.<\/p>\n

Permutation when all the objects are not distinct.
\n1. The number of permutations of \u2018n\u2019 objects, where \u2018p\u2019 objects are of the same kind and rest all different = \\(\\frac{n !}{p !}\\)<\/p>\n

2. The number of permutations of ‘n’ objects, where \u2018p1\u2019 objects are of one kind, \u2018p2\u2019 objects are of the second kind, …….., ‘pk<\/sub>‘ objects are of a kth kind and rest all different = \\(\\frac{n !}{p_{1} ! p_{2} ! \\ldots p_{k} !}\\)<\/p>\n

III. Combinations<\/span>
\nA combination is a selection of some or all of a number of different objects (the order of selection is not important). The number of selection of ‘n’ things taken ‘r’ at a time is n<\/sup>Cr<\/sub>.
\n\"Plus<\/p>\n
