$P(x) = \frac{3-x}{10}$ for x =

$-1$

Explanation

$P(x), pmf=\left.\{ \begin{matrix} \dfrac { 3-x }{ 10 } , & x=-1,0,1,2 \\ 0, & otherwise \end{matrix} \right.$

$E(x)=P(-1)+P(0)+P(1)+P(2)$

$E(x)=\left (\dfrac {3+1}{10}\right)+\left (\dfrac {3-0}{10}\right)+\left (\dfrac {3-1}{10}\right)+\left (\dfrac {3-2}{10}\right)$

$E(x)=\left (\dfrac {4+3+2+1}{10}\right)$

$E(x)=\left (\dfrac {10}{10}\right)$

$\boxed {E(x)=1}$
