Hi everyone can someone help me with my simulation program:

Here is the problem:
An Ambulance are dispatched at a rate of one every 15 + 10 minutes in a
large metropolitan area. Fifteen percent of the calls are false alarm
which requires 12 + 2 minutes to complete. All other calls can be one of
two kinds. First kind are classified as serious. They constitute 15% of
the non-false alarm calls and take 25 + 5 minutes to complete. The
remaining call take 20 + 10 minutes to complete. Assume that there are
very large number of available ambulance, and that any number can be on
call at any time. Write a program that would simulate the system???s 500
call to be completed.

i think it is similar to this topic:
