The document discusses permutations and combinations. It defines permutations as different arrangements that can be made by selecting objects in a given set, where order matters. The fundamental principles of multiplication and addition for permutations are explained. Factorial notation is introduced to calculate the number of permutations when objects are distinct. Examples are provided to illustrate permutations calculations.
4. FUNDAMENTAL PRINCIPLE OF MULTIPLICATION
If there are two operations such that one of them can be performed in m
ways, and when it has been performed in anyone of these m ways, the
second operation can be performed in n ways then the two operations in
succession can be performed in
(m n) ways.

6. FUNDAMENTAL PRINCIPLE OF ADDITION
If there are two operations such that they can be performed
independently in m and n ways respectively then either of the two
operations can be performed in (m + n) ways.

8. PERMUTATIONS
The different arrangements which can be made out of a given number of
things by taking some or all at a time, are called permutations.
In permutations, the order of arrangement of the objects is taken into
consideration. When the order is changed, a different permutation is
obtained.

FACTORIAL NOTATION
Let n be a positive integer. Then, the continued product of first n
natural numbers is called factorial n, to be denoted by n !, or n . Also,
we define 0 ! = 1.
When n is negative or a fraction, n ! is not defined.
Thus, n ! = n(n - 1) (n - 2)3 . 2 . 1.
