Does simulation always give me the right answer, or even a single one?

No, it does not in either case. Simulation provides a platform for the development of models. Simulation can be contrasted with “closed-form” mathematical solutions to problems, which give an exact answer — think queueing models. Because closed-form models can be very unwieldy and complex to develop and explain to non-mathematicians, we increasingly rely on software that allows us to model ideas via a graphical user interface (GUI) and then run and test our model using the underlying simulation engine.
