Monte-Carlo Analysis

- Customer: I've been doing risk analysis by hand for five years, and we finally got your program so we could do it automatically -- but there's a bug in it. The answers come out differently each time.

- Tech Support: Sir, are you aware that our program uses Monte-Carlo analysis?

- Customer: Of course I am. That's why I bought it.

- Tech Support: Sir, do you know what Monte-Carlo analysis does?

- Customer: Don't get rude with me, of course I do.

- Tech Support: Put briefly, sir, it runs through your project several times, throwing random delays in, and at the end it averages out the results.

- Customer: I know all that -- what I want to know is why it keeps giving me different answers every time I run it.
