What is $\frac{1}{\aleph_{\text{0}}}$?

If you have a uniform distribution over the set of natural numbers, what is the probability of any of the numbers being picked? Can you think of it in terms of $\frac{1}{\aleph_{\text{0}}}$?

It's complicated, because there is a problem - $\frac{1}{\aleph_{\text{0}}}$ is undefined. This is because for any finite cardinal $\kappa$, $\kappa \aleph_0 = \aleph_0$. If $\kappa$ was infinite, $\kappa \aleph_0 = \max(\kappa,\aleph_0)$. Therefore, there does not exist a $\kappa$ such that $\kappa \aleph_0 = 1$. Note that $\aleph_0 \cdot 0 = 0$.
