Permutation when all the Objects are not Distinct Objects
The number of permutations of n objects, where p objects are of the same kind and all the rest are different = . In fact, we have a more general theorem.
The number of permutations of n objects, where p1 objects are of one kind, p2 are of second kind, ......, pk are of kth kind and the rest, if any, are of different kind is .
Find the no. of permutations by using the letters of the word EVERONN.
In the word of EVERONN,
Number of letters in the word EVERONN = 7
E occurs 2 times, N occurs 2 times
No. of permutations =
