What are the odds of picking any random number out of an infinite set of numbers?

I’ll just explain why I have come to this question here. I was thinking about the multiverse thing. It occurred to me that if the multiverse is real, as in an infinite quantity of universes, then there is an infinite number of universes where you exist in every variation and an infinite number of universes where you don’t exist in every variation. So if, at random, a portal links two universes together, there is a chance that you will link to a universe with another version of you. It seems like the probability of this would he low, but not zero, despite the fact there would be infinitely more universes without a version of you than there would be with one.

The probability of choosing any 1 outcome from an infinite span, is the span between the lowest possible non-zero number, and zero itself. While in some sense it’s not zero, it IS zero, effectively. It is a 1 preceded by an infinite number of 0’s, which you can describe *conceptually,* but this can’t actually exist as a realistic number.

Infinity breaks things. A truly infinite set isn’t quite comparable to a finite but immense set.
