I suspect that the bet that means that the player bets
Rise to a single number, not in one of
paris combination possible.
The odds of winning 1 / 37
36/37 chance of losing
If you win, you win $ 35 + $ 2 = $ 37
If you lose, you lose profit or $ 2 - $ 2
Thus, the expected benefits are
(1 / 37) * $ 37 + (36/37) *- $ 2
$ 1 - (72/37 $)
apriximately or a loss of $ 0.95

The chances of losing or 1-1/37 = 36/37
Expected profit =
P [win $] * 35 $ + P [miss] * -2 $
= 35/37 = -37/37 + -72/37 = -1 $ $
You will lose one U.S. dollars on average!
