query help - aggregate function

Hi:

I have a table:
EmployeeID   Score
-------------   --------
1                  100
2                     40
3                     40

I want to find out the average score of all employees and the percentage of employees whose score is above average IN ONE QUERY. That is, in this case, the query should return 60 and 0.333. Anyway I can do this? Thanks.

Thanks angelIII. I think that'll do it. However, in reality the base table is in fact a result of a complicated sub-query, I don't feel like repeating it in the query. Is there any other way to do it?
with sql server 2005, you can use the CTE (common table expression).
with SQL server 2000 or lower, you could only store the results of the query into a table variable (or temp table), and continue processing from there.
