Question

why does a coin falling on its edge not considered a event... Because even if its rare but, it IS happening?

Answer 1

Well it's not like it's not considered. That's why usually in the question you see the coin referred to as an unbiased coin. In any case, there's no mathematical expression for a coin falling on its edge and its assumed the coin just doesn't do that. I'm just happy they're not including it in our portion, aren't you?
