<pre>

Winnings   Probability        Expectations
--------------------------------------------------
1900+18       1/757      1918(1/757)=  2.533685601
-18         756/757   (-18)(756/757)=-17.97622193
--------------------------------------------------
                  Total expectation =-15.44253633

If the same lottery were held many times and 757 tickets
were sold every time, and you bought 1 ticket every time,
then by the time you'd have played about 757 times, you'd 
have won about one time and you'd have averaged having 
lost about $15.44 per game.

Answer = -$15.44
