Hmm, you're quite right. My intuition is that the Bayesian portion would exactly offset the Monty hall portion. I think, at a glance, Bayes would give door 1 a 2/3 probability of having 6 gold, but Monty Hall would give door 2 the same probability, so we can effectively cancel these out and just consider a raw probability
You either have 5 gold or 2 gold 3 silver behind door 1, and 6 gold or 3 and 3 behind door 2, which gives door 2 a very slight edge. Does that check out?
Yes! Cancels out, leaving only a very slight edge on door 2. All that work for only... 2.77% edge over picking at random. What a troll problem, huh?
Heh what a trolly problem indeed
Speaking of trolls I assume the madman has perfect knowledge of the layout, hence did not pick a ball out at random.
