What Is the Probability of a 2 on the Roulette Wheel?

There are many casinos in the world that offer roulette as one of their main games. In roulette, a ball is spun around a wheel with 37 or 38 numbers on it.

The ball will eventually land in one of the numbered slots, and whichever number it lands on is the winning number.

The probability of any given number coming up is 1/37 or 1/38 (depending on whether the wheel has 37 or 38 numbers), but this doesn’t take into account the fact that there are actually 18 red numbers and 18 black numbers. If we take this into account, then the probability of any given number coming up becomes 1/18 for red and black each.

Now, let’s look at the probability of a 2 coming up. There are 37 or 38 total numbers, and only 1 of those is a 2.

So, the probability of a 2 coming up is 1/37 or 1/38.

To put it another way, the probability of NOT hitting a 2 is 36/37 or 37/38. The probability of hitting a 2 is therefore 1 – (36/37) or 1 – (37/38), which is the same as 1/37 or 1/38.
