MySQL create stored procedure fails but all internal queries succeed alone?

I just created a simple database in MySQL, and I am learning how to write stored proc's. I'm familiar with M$SQL and as far as I can see the following should work:

use mydb;
-- --------------------------------------------------------------------------------
-- Routine DDL
-- --------------------------------------------------------------------------------
DELIMITER //
CREATE PROCEDURE mydb.doStats ()
BEGIN

CREATE TABLE IF NOT EXISTS resultprobability (
 ballNumber INT NOT NULL ,
 probability FLOAT NULL,
 PRIMARY KEY (ballNumber) );

CREATE TABLE IF NOT EXISTS drawProbability (
 drawDate DATE NOT NULL ,
 ball1 INT NULL ,
 ball2 INT NULL ,
 ball3 INT NULL ,
 ball4 INT NULL ,
 ball5 INT NULL ,
 ball6 INT NULL ,
 ball7 INT NULL ,
 score FLOAT NULL ,
 PRIMARY KEY (drawDate) );

TRUNCATE TABLE resultprobability;

TRUNCATE TABLE drawprobability;

INSERT INTO resultprobability (ballNumber, probability)
(select resultset.ballNumber ballNumber,(count(0)/(select count(0) from resultset)) probability
  from resultset
  group by resultset.ballNumber);

INSERT INTO drawProbability (drawDate, ball1, ball2, ball3, ball4, ball5, ball6, ball7, score)
(select distinct r.drawDate, a.ballnumber ball1, b.ballnumber ball2,
 c.ballnumber ball3, d.ballnumber ball4, e.ballnumber ball5,
 f.ballnumber ball6,g.ballnumber ball7,
((a.probability + b.probability + c.probability + d.probability + e.probability + f.probability + g.probability)/7) score
from resultset r
 inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 1) a on a.drawdate = r.drawDate
 inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 2) b on b.drawdate = r.drawDate
 inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 3) c on c.drawdate = r.drawDate
 inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 4) d on d.drawdate = r.drawDate
 inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 5) e on e.drawdate = r.drawDate
 inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 6) f on f.drawdate = r.drawDate
 inner join (select r.drawDate, r.ballNumber, p.probability from resultset r inner join resultprobability p on p.ballNumber = r.ballNumber where r.appearence = 7) g on g.drawdate = r.drawDate
 order by score desc);

END
//
DELIMITER ;

instead i get the following

Line 1, column 1

What am I doing wrong? I seem to have exhausted my limited mental abilities!

After following suggestions about removing the insert ... select mapping and re-run, I get the following error

"all internal queries succeed alone"

No, they don't, the first usual supect here failed, the:

INSERT INTO drawProbability (...) (select...

Lose the '(' before select, rerun, retest, solve next syntax problem. Being eager for a solution is no reason to skip basic error checks and especially do not claim to have run them if you didn't.
