Question 1110287
Suppose you are invited to play a game in which you bet​ $1 on any number from 000 to 899.
. 
If your number comes​ up, you get ​$675
. 
Find the expected winnings. 
-----
Random "winnings".... -1......674
Probabilities::......899/900...1/900
------
Expected "winnings" = (-899 + 674)/900 = -225/900 = -25 cents
