The following table contains the probability distribution for X = the number of retries necessary to successfully transmit a 1024K data package through a double satellite media.
$$\begin{array} { | c | c c c c | }
\hline \boldsymbol { x } & 0 & 1 & 2 & 3 \
\hline \boldsymbol { p } ( \boldsymbol { x } ) & 0.35 & 0.35 & 0.25 & 0.05 \
\hline
\end{array}$$
-If X and Y are independent variables,then their coefficient of correlation $\rho$ = 0.

Quizplus · Accepted Answer

The coefficient of correlation is only applicable for two continuous variables, not for discrete variables like X and Y in this problem. Therefore, the correlation between X and Y is undefined and can be assumed to be zero.
