In summary, the reference discusses the use of Gaussian probabilities and the calculation of the probability for a finite or infinite universe based on the spatial curvature parameter Ωk. The paper presents a value of Ωk with a standard deviation, but this does not necessarily reflect the actual probability of the universe being positively curved. The question of whether the universe is finite or infinite is still open and cannot be determined solely based on these calculations.
And with that, this thread is closed. @Buzz Bloom you can PM me if you have further questions about what I have said. We have beat this topic more than enough for a public thread.
