![For a group of four 50-year-old men, the probability distribution for the number \( x \) who live through the next year is as given in the table below.
\[
\begin{array}{|c|c|}
\hline
x & P(x) \\
\hline
0 & 0.0003 \\
1 & 0.0082 \\
2 & 0.0798 \\
3 & 0.3467 \\
4 & 0.5650 \\
\hline
\end{array}
\]
Verify that the table is indeed a probability distribution. Then find the mean of the distribution.
