OK, lighting the blue touchpaper.
I understand the monty hall problem.
Does deal or no deal work the same way? If you keep your box you've got 1/30 chance but if you swap at the end you've got a 29/30 chance, assuming the top prize hasn't already gone?

No, not the same.

The host in the Monty Hall problem knows where the prize is, so is adding information to the system when they open a door.

This part is absolutely critical to how the original problem works.

This.


I didn't believe it at first.

But it works.

Indeed, Deal or No Deal is a completely different concept. True, there's only a 1/30 chance you have the top prize, and there's a 29/30 chance it's elsewhere, but you don't know where, and ultimately, you've got to pick a box at random. You might as well stick with your original. The concept is also different as every box has a value so high, some low. In the Monty Hall problem, only 1 box has a value.

Goats aren't entirely without value, a quick google suggests around the hundred and fifty nicker mark.

But how many people have the facilities to keep or even transport it? It's a bit like someone from an inner city sink estate who doesn't own a car wining Bully's Star Prize...a frigging speedboat!

I don't think they ever actually got to keep the goat, it was a metaphor for a worthless prize.

I'm really not sure I was being entirely serious. wink
