Probability cannot predict the exact outcome of a single Roulette spin because each spin is an independent event with random results. While probability can tell you the likelihood of a specific result, such as a 1 in 37 chance (for European Roulette) of landing on a particular number, it cannot provide certainty. Factors like the house edge and randomness mean that no pattern or formula can accurately predict outcomes over time. Although understanding probability helps with making informed bets, it does not guarantee a win on any given spin.
