As an individual investor, you have three funds to invest into. The first is an equity fund, the second is a corporate bond fund, and the third is a T-bill money-market fund (your risk-free asset).

Fund	Expected rate of return	Risk (Standard deviation)
Equity fund	18%	32%
Corporate bond fund	9%	20%
T-bill money market fund	5%

Correlation between equity fund and bond fund returns is 0.4.

Find the risk (standard deviation) of the minimum variance portfolio formed from Equity and Bond funds.
