Answer:

Explanation:

To find the Standard Deviation:

First find expected return.

(0.7*100%)+(0.3*-50%) =70-15= 55%

Then the Variance.

[0.7*(1-0.55)^2]+[.3*(-0.5-0.55)^2]

=0.14175+0.33075

=0.4725

=47.25%

The Standard Deviation is the square root of the variance.

$\sqrt{0.4725}$

=0.6874

=68.74%
