On average how often black hits in roulette?

In European roulette, which has 37 pockets numbered from 0 to 36, the probability of the ball landing on a black number is 18/37, or approximately 48.65%. For double zero roulette it is 47.3%/. However, it's important to note that each spin of the roulette wheel is an independent event and the outcomes of previous spins do not affect the probability of future spins. Therefore, there is no guarantee that black will hit any specific number of times in a given number of spins.
