Grouping the two doors you did not select together is a fallacy. They are not collectively 2/3rds of the equation, they are always 1/3rd each. When one is removed, the value of the removed door is divided equally between the two remaining doors.

That has no relevance at all. He's always going to open a losing door no matter which door you picked. You learn absolutely nothing when he opens the door.

It's just a simple consequences of the definition of conditional probability. And the generalization of conditional probability is very useful in statistics, including the generalized form of bayes' formula.

Yeah but you didn't know which of the two doors he would choose.

While you are mulling over your retarded goat car conundrum (((monty hall))) is directing (((crew members))) to move the car and goat around behind the doors hth.

>> No.10612789

So basically abstract statistic dick inflections say that you always have to switch because your chances go up from 33% to 50% after the door with the goat has been revealed but in reality if you were to run the experiment it wouldn't actually make any difference because opening one of the doors with the goat doesn't influence in which door the car will be.

/g/ here. Imagine I'm going to code a simulation. How do I pick which door monty opens? Assume the player originally picked the car. There are two goats. Do I need to pick randomly or can I just pick door 1 every time?

>> No.10612882

>>10612875
randomly

>> No.10612885

>>10612875
You can always select door 1 and open the lowest one with a goat that's not selected (so 2 or 3) as long as the car is random. Then you can switch or not.

The maths say yes if you desire the car. But why is the care more valuable than a goat? To answer that we need sociology. Sociology is beyond /sci/'s grasp.

Imagine you had a billion doors, and behind one of them was a jeep while the rest were goats. You pick door 1 while the show host opens every door except for door 1 and door 28349855, do you switch?

>> No.10613794

>>10612093
For anyone not understanding why switching increases your chances, just imagine 100 doors (1 win 99 losers) instead of three:
Moderator asks you to pick one out of 100 doors.
You randomly choose one.
Moderator opens up 97 doos of the 99 not chosen doors, all of them losers.
Only 3 doors remain, one being the winner.
Do you switch?

>> No.10613914

>>10613794
Yes, because if I switch my chances goes from 1% to 33%

Many of the solutions posted here involve probability or arithmetic. However, it is possible to solve this using only pure logic / set theory.

>> No.10614084

Has anyone watched all the episodes and figured out the times that switching would have been better vs staying?
