Question
Number of different permutations of the word 'BANANA' is
- 60
- 40
- 35
- 50
Hint:
First of all, we have to find the total number of words formed by BANANA. We know the formula that the total number of permutations of n items in which m items are the same is equal to 
The correct answer is: 60
In this question, one might think that the total number of permutations for the word BANANA is 6!
This is wrong because in the word BANANA we have the letter A repeated thrice and the letter N repeated twice.

The number of ways in which 17 billiard balls be arranged in a row if 7 of them are black, 6 are red, 4 are white is
We cannot arrange the billiards balls as follows:
There are 17 balls, so the total number of arrangements = 17!
This is incorrect because this method is applicable only when the balls are distinct, not identical. But, in our case, all the balls of the same color are identical.

The number of different signals that can be made by 5 flags from 8 flags of different colours is :
Each of the different arrangements which can be made by taking some or all of a number of things at a time is called permutation. 
Thus we can say that the permutation concerns both the selection and the arrangement of the selected things in all possible ways.
