Why, when the chances of a certain event are 1/10, it's read as `the probability is ten to one` and not "the probability is one to ten"? Like there's a `10/1` probability of occurrence, which is not possible, since it's limited within `0~1` range. The way it's written in arithmetic notation is pretty straightforward, reading it backwards doesn't make sense to me. How did it come to be like that?
