"The spatial anomaly has interacted with the tachyonic radiation in the nebula, it's interfering with our sensors. It's impossible to get a reading."
"There's no time - we'll have to take the ship straight through it!"
"Captain, I advise against this course of action. I have calculated the odds against our surviving such an action at three thousand, seven hundred and forty-five to one."
"Damn the odds, we've got to try... wait a second. Where, exactly, did you get that number from?"
"I hardly think this is the time for-"
"No. No, fuck you, this is exactly the time. The fate of the galaxy is at stake. Trillions of lives are hanging in the balance. You just pulled four significant digits out of your ass, I want to see you show your goddamn work."
"Well, I used the actuarial data from the past fifty years, relating to known cases of ships passing through nebulae that are interacting with spatial anomalies. There have been approximately two million such incidents reported, with only five hundred and forty-two incidents in which the ship in question survived intact."
"And did you at all take into account that ship building technology has improved over the past fifty years, and that ours is not necessarily an average ship?"
"Indeed I did, Captain. I weighted the cases differently based on how recent they were, and how close the ship in question was in build to our own. For example, one of the incidents with a happy ending was forty-seven years ago, but their ship was a model roughly five times our size. As such, I counted the incident as having twenty-four percent of the relevance of a standard case."
"But what of our ship's moxie? Can you take determination and drive and the human spirit into account?"
"As a matter of fact I can, Captain. In our three-year history together, I have observed that both you and this ship manage to beat the odds with a measurable regularity. To be exact, we tend to succeed twenty-four point five percent more often than the statistics would otherwise indicate - and, in fact, that number jumps to twenty-nine point two percent specifically in cases where I state the odds against our success to three significant digits or greater. I have already taken that supposedly 'unknowable' factor into account with my calculations."
"And you expect me to believe that you've memorized all these case studies and performed this ridiculously complicated calculation in your head within the course of a normal conversation?"
"Yes. With all due respect to your species, I am not human. While I freely admit that you do have greater insight into fields such as emotion, interpersonal relations, and spirituality than I do, in the fields of memory and calculation, I am capable of feats that would be quite simply impossible for you. Furthermore, if I may be perfectly frank, the entire purpose of my presence on the bridge is to provide insights such as these to help facilitate your command decisions. If you're not going to heed my advice, why am I even here?"
"Mm. And we're still sitting at three thousand seven hundred to one against?"
"Three thousand, seven hundred and forty five to one."
"Well, shit. Well, let's go around, then."
