Calculate the standard deviation of a portfolio with 0.24 invested in Asset A, 0.34 invested in Asset B, and the rest invested in Asset C. Express your answer as a decimal with four digits after the decimal point (e.g., 0.1234, not 12.34%).

Std Dev(rA) = 0.48, Std Dev(rB) = 0.69, Std Dev(rC) = 0.51

Correlation(rA,rB) = -0.25, Correlation(rA,rC) = 0.27, Correlation(rB,rC) = 0.06
