Unlike the cosine, which has grown tarnished and shriveled with the oxidation of centuries, the Law of Large Numbers (LLN) has kept remarkably well. As I crept through my apartment over the course of the next few days, expecting a black and orange and mud-coloured assault at every step, I recited the Law to myself.
The LLN states that, when one has the results of a large number of trials from a sample that is representative of a given population, the average of said results should be close to the expected value of the population entire. This sample average will tend closer to the population average as more trials are performed. Since the average number of humans killed or injured by klars per Old Earth Lunar Year (OELY) in the past few decades was precisely zero, and this constituted a good number of trials, the LLN would have me believe that I was safe. I should have gone forth boldly, and stopped slouching so much.
But under these circumstances – as close as I thought I would ever get to experiencing the antique ‘horror’ genre, in which I have precisely zero interest – it was difficult to convince myself that klars had not simply been saving the lives of the same number of human as they killed every year, thus ensuring a neutral profile for the species entire. Having an invisible beast with untrimmed, inch-long claws in one’s living quarters has this sort of effect.
