Random 'winnings'............. 35......-1
Corresponding probabilities:: 1/38...37/38
Expected 'winnings' = [35-37]/38 = -2/38 = -1/19 = -$0.05 dollars

Roulette 0 1 2 3/4Basket - The payout will be 6 to 1 (with a percentage chance of 13.2% in American roulette, this bet is not found in European roulette) as you are betting on five numbers (i.e. 0, 00, 1, 2, 3). The odds of 0 spinning three times in a row are 1 in 50653. But the odds of 0,0 then 2 spinning are exactly the same. The odds of any number spinning next are the same. EXAMPLE 2: You may wait for the first dozen to spin three times consecutively, then bet on the second and third dozens.
