A certain brand of cars captured 17% of the market. If 3 cars are selected at random, the probability distribution is given below. Find E(x).

\[
\begin{array}{c|cccc}
x & 0 & 1 & 2 & 3 \\
\hline
P(x) & 0.2 & 0.4 & 0.1 & 0.3 \\
\end{array}
\]

What is the expected value?

E(x) = [    ] (Type an integer or a decimal.)
