So the probability, if you have a mean of minus 5 and a standard deviation of 10, the probability of getting 1,000 here is very, very low. But there is some probability that all of the atoms in my body just arrange perfectly that I fall through the seat I'm sitting on. It's very unlikely. And it probably won't happen in the life of the universe. But it can happen. And that could be described by a normal distribution. Because it says anything can happen, although it could be very, very, very unprobable.
