Need SQL Query Help

OK I am tring to create a query and I am not sure how to do it.

example query:

select fcr, count(fcr) from incidents group by fcr;

FCR COUNT(FCR)
--- ----------
N/A 3466
No 8844
Yes 111968

Now what I want is this

FCR COUNT(FCR) % of total
--- ---------- -------------
N/A 3466 0.02
No 8844 0.07
Yes 111968 .91

FOr the life of me I just cant figure this out. ANd I know that it is going to be a really simple answer.

Thank you for any help you can offer

Something like this should do the trick

sql Code:

Original - sql Code
select fcr, (count(fcr)/(select count(fcr) from incidents)) from incidents group by fcr;

SELECT 
fcr, 
(COUNT(fcr)/(SELECT COUNT(fcr) FROM incidents)) 
FROM incidents 
GROUP BY fcr;

Thank you, I knew I was over thinking it way to much.

OK that worked for oracle 9i but when I try in
SQL*Plus: Release 8.1.6.0.0 - Production
I get the following error

SQL> select fcr, count(fcr), (count(fcr)/(select count(fcr) from incident))*100 "%" from nx_winch_case_details group by fcr;

select fcr, count(fcr), (count(fcr)/(select count(fcr) from incident))*100 "%" from nx_winch_case_details group by fcr
*
ERROR at line 1:
ORA-00979: not a GROUP BY expression

where the * is under the count(fcr) from the nested select statement.
