Now I will explain you what does it mean.
At the first spin, you will get one of the three colors. Any one of the three.
At the second spin you want to get DIFFERENT color from what you get at the first spin.
The probability of it is , obviously.
At the third spin, you want to get the THIRD different color.
The probability to get it is , obviously.
It gives you the answer.
