The probability of hitting an even number depends on the total set of numbers being considered. In general, if you're looking at a sequence of consecutive integers (for example, 1 to 10), half of them are even. Thus, the probability of randomly selecting an even number in such a case would be 50%. If the range or set of numbers changes, the probability can vary accordingly, but for large sets of integers, the likelihood of selecting an even number tends to remain close to 50%.
What is the probability of hitting an even number?

You are correct in pointing out that in a standard set of consecutive integers, the probability of hitting an even number is 50%. This is because every other number is even and every other number is odd, making the ratio 1:1 or 50% for each outcome.
When it comes to roulette, the situation is a bit different, as the numbers are not simple integers running from 1 to 36. In the classic European roulette wheel, there are 37 numbers (0-36), with 18 of these numbers being even and 18 being odd. The additional number is the green 0, which is neither even nor odd.
Therefore, in the context of European roulette, the probability of hitting an even number on any given spin is approximately 48.65% (18/37), assuming a fair wheel with no bias. This is slightly less than 50% due to the presence of the 0, which is neither even nor odd.
It's important to note that these probabilities are based on the assumption of a fair roulette wheel, and factors such as wheel bias or imperfections can affect the actual outcomes in a real-world casino setting.
