An Investor Is Considerinq the Three Equities Given Below Calculate the Expected Return and Beta of a Portfolio Equally

An investor is considerinq the three equities given below:
$\begin{array} { | l | l | l | } \hline \text { Equity } & \text { Expected Return } & \text { Beta } \\\hline \text { A } & 6.0 \% & - 0.10 \\\hline \text { B } & 13.3 \% & 2.10 \\\hline \text { C } & 9.2 \% & 0.75 \\\hline \text { Market Portfolio } & 10.0 \% & 1.00 \\\hline \text { T-Bills } & 7.0 \% & 0.00\end{array}$
Calculate the expected return and beta of a portfolio equally weighted between equities B and C. Demonstrate that holding equity A actually reduces risk by comparing the risk of a portfolio equally weighted between equity B and T-Bills with a portfolio equally weighted between equity B and A.
