Short Answer

Instruction 5-5
There are two houses with almost identical characteristics available for investment in two different neighbourhoods with drastically different demographic composition.The anticipated gain in value when the houses are sold in 10 years has the following probability distribution:
Returns
$$\begin{array} { | c | c | c | } \hline \text { Probability } & \text { Neighbourhood A } & \text { Neighbourhood B } \\\hline .25 & - \$ 22,500 & \$ 30,500 \\\hline .40 & \$ 10,000 & \$ 25,000 \\\hline .35 & \$ 40,500 & \$ 10,500 \\\hline\end{array}$$
-Referring to Instruction 5-5,what is the total standard deviation of value gain if you invest in both houses?
