Short Answer

SCENARIO 5-1
The following table contains the probability distribution for X = the number of retransmissions
necessary to successfully transmit a 1024K data package through a network. $$\begin{array} { c | c | c | c | c | } X & 0 & 1 & 2 & 3 \\\hline P ( X ) & 0.35 & 0.35 & 0.25 & 0.05\end{array}$$
-Referring to Scenario 5-1, the standard deviation of the number of retransmissions is ________.
