Create the simulation table by hand for the given problem.

An elevator in a manufacturing plant carries exactly $400$ kilograms of material. There are three kinds of material

packaged in boxes that arrive for a ride on the elevator. These materials and their distributions of time between

arrivals are as follows:

It takes the elevator $1$ minute to go up to the second

floor, $2$ minutes to unload, and $1$ minute to return to

the first floor. The elevator does not leave the first

floor unless it has a full load. Simulate $20$ minutes of

operation of the system. What is the average transit

time for a box of material A $($time from its arrival until

it is unloaded$)?$ What is the average waiting time for a

box of material B$?$ How many boxes of material C

made the trip in $20$ minutes?

Use the following random numbers, in the order given:
