a$.$ Assume round robin service is used to schedule outbound service. Each packets class of service, from $1-3,$ is provided in blue above. $1-$ At what times will packets $1$ through $10$ leave the queue $($packet one leaves the queue at t$=1)?2-$ Finally, what is the average of the delay over all $10$ packets?

b$.$ Assume priority service is used to schedule outbound service. Each packets class of service, from $1-3,$ is provided in blue above. $1-$ At what times will packets $1$ through $10$ leave the queue $($packet $1$ leaves the queue at t$=1)?$Additionally, indicate the delay for each packet from when they arrive at the queue until they depart. You may consider whole numbers $($packet $4$ arrives at t$=2\mathrm{.}19,$ but you can say it arrives at time t$=2).2-$ Finally, what is the average of the delay over all $10$ packets?
