\[= 0,2\left( 1 - \frac{1}{2} \bullet {0,2}^{2} + \frac{1}{2} \bullet 1 \right) =\]
\[= \frac{1}{5}\left( 1 - \frac{1}{2} \bullet \left( \frac{1}{5} \right)^{2} + \frac{1}{2} \right) =\]
\[= \frac{1}{5}\left( 1 - \frac{1}{2} \bullet \frac{1}{25} + \frac{1}{2} \right) =\]
\[= \frac{1}{5} \bullet \left( \frac{50}{50} - \frac{1}{50} + \frac{25}{50} \right) = \frac{1}{5} \bullet \frac{74}{50} =\]
\[= \frac{74}{250} = \frac{37}{125}.\]
