It is not too many reds, but it is also not a perfectly balanced roulette wheel.
It is given that the red numbers should come up 18 times when the roulette wheel is played 38 times.
Therefore, the ratio of red numbers to the total number of plays is = 18:38
It is also given that a casino tests the wheel with 3800 plays and noticed that the red numbers came up 1890 times.
The ratio is given as 1890:3800.
We have to simplify this.
1890/3800 = 18.9/38
If the roulette wheel was perfect, it should've been 18:38.
Therefore, we can say that the roulette wheel is not perfectly balanced.
