The golden ratio
On the presumption that it is a cubic die, on average you will not gain nor lose any money. Out of the six faces, 1/3 of them are a 5 or a 2. So 1/3 of the time, you will gain 3$, but will lose 1$ from the initial payment. 1/3 of 3$ is 1$, so on average, you will gain 1$, while losing 1$.
Another way of looking at it is to take the possible out comes, and add the gains/loses, and you will come up with 0$.

<em><u>Number of brown horses are:</u></em>
Therefore, 1/2 of total number of horses are brown
of 120
![\text{ brown horses } = \frac{1}{2} \text{ of } 120\\\\\text{ brown horses } = \frac{1}{2} \times 120\\\\\text{ brown horses } = 60](https://tex.z-dn.net/?f=%5Ctext%7B%20brown%20horses%20%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctext%7B%20of%20%7D%20120%5C%5C%5C%5C%5Ctext%7B%20brown%20horses%20%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20120%5C%5C%5C%5C%5Ctext%7B%20brown%20horses%20%7D%20%3D%2060)
of the horses are black
<em><u>Number of black horses are:</u></em>
Therefore, 1/3 of total number of horses are black
of 120
![\text{ Black horses } = \frac{1}{3} \text{ of } 120\\\\\text{ Black horses } = \frac{1}{3} \times 120\\\\\text{ Black horses } = 40](https://tex.z-dn.net/?f=%5Ctext%7B%20Black%20horses%20%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Ctext%7B%20of%20%7D%20120%5C%5C%5C%5C%5Ctext%7B%20Black%20horses%20%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20120%5C%5C%5C%5C%5Ctext%7B%20Black%20horses%20%7D%20%3D%2040)
of the horses are spotted
<em><u>Number of spotted horses:</u></em>
Therefore, 1/6 of total number of horses are spotted
of 120
![\text{ Spotted horses } = \frac{1}{6} \times 120 = 20](https://tex.z-dn.net/?f=%5Ctext%7B%20Spotted%20horses%20%7D%20%3D%20%5Cfrac%7B1%7D%7B6%7D%20%5Ctimes%20120%20%3D%2020)
