The drive-through for a Hungry Jacks' fast food restaurant operation was studied using simulation to determine a variety of operating characteristics. As part of the study, data was collected on order processing time as given in the following table. Using the random numbers, determine the expected waiting time for a customer to receive an order for simulation with six customers.

\begin{tabular}{|l|l|l|l|l|} \hline Processingtime(min) & 1 & 2 & 3 & 4 \\ \hline Relative Frequency & 0.30 & 0.20 & 0.20 & 0.30 \\ \hline \end{tabular} \begin{tabular}{|l|l|l|l|l|l|l|} \hline Customer & 1 & 2 & 3 & 4 & 5 & 6 \\ \hline Random Number & 0.74 & 0.25 & 0.45 & 0.11 & 0.05 & 0.64 \\ \hline \end{tabular}
