If North American casino roulette were fair, how much should it pay to a player who bets $100 on black and a black number comes up? The odds against winning a bet on a black in roulette are 1.01 to 1.
------
P(no black) = 1.01/2.01
P(black) = 1/2.01
-------------------------------
Let the casino payoff be "x" dollars:
----------------------------------------
Random values of casino gain: 100-x ; 100
Corresponding Probabilities: 1.01/2.01 ; 1/2.01
---
Note: If game is "fair" E(x) = 0
---
[1.01/2.01](100-x) + [1/2.01]100 = 0
---
Multiply thru by 2.01 to get:
101-1.01x + 100 = 0
1.01x = 201
x =$199.01 (amt. casino should offer to pay if player wins on "black")
