It depends on whether the agent that opened the door was knowing, or whether it's coincidence.

I'd say there's a probability of 99/100 that it contains a person who've landed on his head 1/3 of the time while being male 2/3 of the time.

50/50

>>4119476
at the beginning: 1% chance of being your door, 99% of being any of the others
eliminate 98 of the empty doors, there's still a probability of 99% that it's in one of the 99 you didn't pick. How does it matter whether he's knowing or not?

>>4119471
This.
/thread

there is a 1 out of 2 chance in my humble opinion

You only choose once, so the initial chance (1%)

The probability of the outcome depends on what initial conditions conditions you choose to work with and what assumptions you make. The question is ambiguous. Anyone that strongly favors ANY answer to this question is wrong.

This is just yet another bastardized version (seriously there's been like fucking over 9000 of these) of the boy/girl paradox please stop posting this shit already.

It's 99% likely that your door has money behind it.
As each door opens the odds of your door being the winner is increased.
Using the same scenario with 3 doors, when it comes to being only 2 doors left, your door has a 66 percent chance of being the winner.

but if the money was inside the door and not in the room to which the doors lead, then opening the doors wouldn't tell you much about where the money is. you'd have to crowbar the doors to be able to see inside them.

I disagree, as the problem is really only fully introduced when you've opened all the doors but yours and the 1$M prize one. If the question had been:

What is the chance of someone opening all the doors but yours and one another and that one another is the 1$M prize? The answer would be different.

But the 98 doors are in fact discarded from the problem, so there are only 2 doors remaining, leaving it to 50/50.

With 99% probability the other door will have the prize.

So 1%.

Your door:1/100
Other door:99/100

This would have been an interesting troll thread had I not seen the Monty Hall problem before. 3/10.
