Of course, knowing this, Monty could only offer that choice to change when the item is actually behind the chosen door.

It’s a posterior probability problem. Like I said, Look to Reverend Bayes for guidance. He was Isaac Newton’s math tutor, so he probably knew what he was talking about.

No, he could offer it all the time. He just has to reveal the door with no car. The information Monty reveals is "insider info", he is never going to show you the car and ask you to choose.

Love the Monty Hall dilemma and loved the show too...

It's the same as the principal of restricted choice.

Your choices are A, B and C. You pick A.

If it is A you win by sticking to A.

If it is B, Monty shows you C. You win by switching.

If it is C, Monty shows you B. You win by switching.

Switching is right 2/3 of the time.

Yes, if he offers it all the time, the switch wins. But did anyone ever actually review the tape to see if he offered it all the time? I seem to recall that sometimes he offered a box or an envelope in exchange for the curtain.

I think KenPom calculated Monty's BD3* numbers.

Yes, I reviewed the tape. He always offers it. He sometimes offers an envelope or box in other games but usually only to grumpy, old empiricists who troll the show.

I'm never grumpy. Nor bashful.

Right now, I'm sure you can provide a layman's explanation, just as I was able to show Colin that there is no natural source of CO2 to explain the increased concentration in the atmosphere and that it is directly correlated to world temperature.


And Colin understood?

Probably chalks it up to the seltzer machines running overtime in the Northeast.

Anyone who says CO2 can't possibly have an impact because it's a trace element in the atmosphere should try seeing what digesting a trace amount of arsenic does.

It’s always creepy when this hobby and my actual work cross, but the Monty Hall problem is actually my preso open for a workshop session I’m leading next month. This whole thread is weird, but that’s creepy.
