Given:

The probability distribution is,


\begin{gathered} x=-4,-3,-2,-1,0,1,2,3,4 \\ p(x)=0.02,0.07,0.11,0.14,0.33,0.17,0.09,0.06,0.01 \end{gathered}

The mean is calculated as,


\begin{gathered} \mu=\sum ^{}_{}xp(x) \\ =-4(0.02)+(-3)(0.07)+(-2)(0.11)+(-1)(0.14)+0(0.33)+1(0.17)+2(0.09)+3(0.06)+4(0.01) \\ =-0.08 \end{gathered}
