If you said there was a 3.1% chance that a gun was going to be fired in a random location on the planet and kill 10,000 people in that area, the probability of both those things happening and affecting you is negligible.

Note: I didn’t say kill.

Well then get used to this risk, because this sized rock was a once-a-century level event. You were living with this risk every year and you just didn’t know it.
