=25/37
1-P(Not landing on the number) =
Assuming 25 spins in a row (50 euros, 2 at a time),
1-(36/37)^25 = .4958968427
You have 25 (i.e., 50/2) games to play before running out of Euro’s. On any given game, the odds of losing is 36/37 (= 97.297%). So, in 25 tries, the odds of losing all games in a row is 0.97297^25 (= 50.410%). Thus, the chance of winning once during the 25-game run is
(100% – 50.410%), which is 49.590%.
