Determine Whether the Distribution Represents a Probability Distribution $$\begin{array} { c | c } x & P ( x ) \\\hline 1 & 0.2 \\2 & 0.2 \\3 & 0.2 \\4 & 0.2 \\5 & 0.2\end{array}$$

Short Answer

Determine whether the distribution represents a probability distribution. If not, identify any requirements that
are not satisfied. $$\begin{array} { c | c } x & P ( x ) \\\hline 1 & 0.2 \\2 & 0.2 \\3 & 0.2 \\4 & 0.2 \\5 & 0.2\end{array}$$
