Suppose an event occurs in the world that you deem to be dissimilar enough to all other events that have ever happened in the world to consider it unique. Does this imply it is less likely to happen than some other event that is considered similar to other events.
Let’s consider A = the class of events that have atleast one other event similar to it. Let’s consider B = the class of events that have no other events similar to it
If B is a class of one, and A is a class of millions, wouldn’t that imply a unique event is less likely? Or is this a fallacy?
My more general question is whether or not coming across some event that you process as way differently from other events implies a lower probability. If this is a fallacy, what is it called?
