Consider the population described by the probability distribution below. $\begin{array}{c|c|c|c}
x & 2 & 5 & 7 \
\hline p(x) & .2 & .5 & .3
\end{array}$

The random variable $x$ is observed twice. The observations are independent. The different samples of size 2 and their probabilities are shown below.

Find the sampling distribution of the sample mean $\bar { x }$
