Retries
the Following Table Contains the Probability Distribution for X

question 150

True/False

Retries
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 two variables with $\sigma _ { x } ^ { 2 } = 3.25$ , $\sigma _ { y } ^ { 2 } = 5.8$ ,and COV(X,Y)= 14.703,then the coefficient of correlation $\rho$ = 0.78.
