Theorem 2 
2. 
Permutations when all the objects are not distinct objects 
Theorem 3 Theorem 4 

Derivation of the formula for
In this section, you will get to learn how to derive the formula of permutation.
Formula of permutation is given by  ^{n}P_{r} = $\frac{n !}{(nr) !}$ , where 0 ≤ r ≤ n
Theorem 2: The number of permutations of n different objects taken r at a time, where repetition is allowed, is n^{r}.

Permutations when all the objects are not distinct objects
This section has two theorems which you must learn before solving exercise questions. The two main theorems are:
Theorem 3: The number of permutations of n objects, where p objects are of the same kind and rest are all different = $\frac{n !}{p !}$ .
Theorem 4: The number of permutations of n objects, where p1 objects are of one kind, p2 are of second kind, ..., pk are of k th kind and the rest, if any, are of different kind is $\frac{n !}{p_{1} ! p_{2} ! \ldots p_{k} !}$
