Question 420048
six senior level english classes were asked to choose one of eight guidance counslers to make a presentation to their class at some point. 
A What is the probablity that each class chooses a unique counsler? 

i tried 8c6 over 8c8
----
8C8 = 1
I don't think you want that answer.
-----
How about 8C6/8^6 = 28/262144
