Question 324865: Hello, Can someone please explain how I can determine the number of permutation for the work SELECTION the following is my answer but I am not sure if it is right. Thank you.
Determine the number of permutations of the letters of the word “SELECTION.”
ANSWER:
Number of Permutations taking all the letters at a time = 9P9
= 9! = 362880.

I am not sure what topic best fits my question.
Sorry

You can put this solution on YOUR website!
you are kind of on the right track

the problem is the two E's

every permutation will be duplicated

so half of 9P9 is correct
