FactChecker reacted to Roberto Pavani's post in the thread Undergrad Why the initial choice matters in the Monty Hall problem with
Like.
I'm amazed by the length of this thread. In a sense, it confirms what I've often thought about statistics and probability: the rules... -
FactChecker reacted to Ibix's post in the thread Undergrad Why the initial choice matters in the Monty Hall problem with
Wow.
AFAIK, the big difference between the problem and the gameshow is that Monty had other options besides just "open a door". The problem... -
FactChecker replied to the thread Undergrad Why the initial choice matters in the Monty Hall problem.If Monty is allowed to play games, that changes everything and brings game theory into the equation. In that case, there is no way to... -

He never did. It was not a stated rule, but we can infer that he had the knowledge where the car was and used that knowledge to open a... -
FactChecker replied to the thread Undergrad Why the initial choice matters in the Monty Hall problem.Is that right? That is a critical difference. I didn't watch it enough to know if Monte ever opened a door with the prize. I was just... -

It is worth checking Cantor out. -
FactChecker replied to the thread Undergrad Is infinity a necessary concept?.Even with analytic continuation, I doubt that there is any legitimate expansion at a point that allows that conclusion. -

Informative.
I think the OP is probably referring to several pop-sci content (YouTube videos from Numberphile comes to mind) where it is "shown" that... -
FactChecker reacted to dendros's post in the thread Undergrad Is infinity a necessary concept? with
Like.
Considering that the set of integers (which are the simplest math entities) is infinite, I would say that yes, infinity is necessary in... -
FactChecker replied to the thread Undergrad Is infinity a necessary concept?.This doesn't really require infinity, just huge enough numbers to get it done. Space is not infinite. I assume you mean convergence to... -

I mean, the fact that the world of mathematicians generally work with infinities on a daily basis should tell you something about its... -
FactChecker replied to the thread Announcement PF Style 2026.It's still a little smaller font size than I like, but it is legible (for me) without trouble. I'm happy with it, as is. -
FactChecker replied to the thread Announcement PF Style 2026.After people here told me about the Ctrl++, my complaints about the font size all disappeared. That works perfectly for me. -
FactChecker replied to the thread Announcement PF Style 2026.An earlier post recommended using Ctrl++ to zoom in. I didn't know it was that easy. It works well.
