You might look here,
http://contextures.com/functions.html
though I'm not sure whether "functionalities" means something different
to you than "functions".
IIRC, there are over 300 functions.
I've never seen any statistics about % of functions that the average
user knows/uses, though based on my experience, I'd suspect it's in the
low single digits.
The hardest part of that query, I think, is defining what you mean by
"average user".

Does anybody has a count of the number of functionalities that are
available in Excel 2003. Furthermore is that any statistics of the
average excel user % knowledge of these funtionalities?
