Undefined Probablility
Posted:

Hello everyone, this is my first time posting. So, I was sitting in math class today (dozing off, I might add) and thought about just guessing the answer to a problem. This led me to an interesting conclusion. If somebody said "I'm thinking of a number," and asked you to guess what it was, wouldn't you technically have an infinite number of possibilities to answer with? And if so, wouldn't the probability of you guessing correctly be 1/infinity? 1/infinity is undefined. My basic question is, is it possible to have an undefined probability? And if so, why is it possible? Thanks, Justin
