![\rm Expected\ Return= 200\ x\ [(0.10\ x\ 0.01)+(0.40\ x\ 0.04)+(0.50\ x\ 0.08)]\\\\\rm Expected\ Return=200\ x\ 0.057\\\\\rm Expected\ Return=\$11.4](https://tex.z-dn.net/?f=%5Crm%20Expected%5C%20Return%3D%20200%5C%20x%5C%20%5B%280.10%5C%20x%5C%200.01%29%2B%280.40%5C%20x%5C%200.04%29%2B%280.50%5C%20x%5C%200.08%29%5D%5C%5C%5C%5C%5Crm%20Expected%5C%20Return%3D200%5C%20x%5C%200.057%5C%5C%5C%5C%5Crm%20Expected%5C%20Return%3D%5C%2411.4)
