Retries
the Following Table Contains the Probability Distribution for X

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 independent variables with V(X)= 23.48 and V(Y)= 36.52,then the standard deviation of W = X + Y is $\sigma$ _w = 7.746.
