question 113

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 = 3.8, $\sigma$ _y = 4.2,and COV(X,Y)= -0.25,then V(X + Y)= 31.58.
