Step-by-step explanation:
Miguel's choose the best way to win the 2 dollars by pulling the two chips with the number 1. In total, there are four balls, so his probability of winning is:
![\to \frac{2}{4} \times \frac{1}{3}= \frac{1}{6}](https://tex.z-dn.net/?f=%5Cto%20%5Cfrac%7B2%7D%7B4%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%3D%20%5Cfrac%7B1%7D%7B6%7D)
The chances of losing a dollar add up to that amount, so 5/6.
Price predicted = ![\frac{1}{6} \times (2) + \frac{5}{6} \times (-1)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%20%5Ctimes%20%282%29%20%2B%20%5Cfrac%7B5%7D%7B6%7D%20%20%5Ctimes%20%28-1%29)
![=\frac{1}{6} \times 2 + \frac{5}{6} \times -1\\\\=\frac{1}{3} - \frac{5}{6} \\\\=\frac{2-5}{6}\\\\=\frac{-3}{6}\\\\=- \frac{1}{2}\\](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B6%7D%20%5Ctimes%202%20%2B%20%5Cfrac%7B5%7D%7B6%7D%20%20%5Ctimes%20-1%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B3%7D%20-%20%5Cfrac%7B5%7D%7B6%7D%20%20%20%5C%5C%5C%5C%3D%5Cfrac%7B2-5%7D%7B6%7D%5C%5C%5C%5C%3D%5Cfrac%7B-3%7D%7B6%7D%5C%5C%5C%5C%3D-%20%5Cfrac%7B1%7D%7B2%7D%5C%5C)
The final answer is "
