  • math had always been so fucking easy!!!!

  • maths have always been fucking easy!!!

  • @PeidoLord Lets say you choose one door from a hundred. That means the chance that you have the pick right is 1/100. Now the presenter closes all but two doors - the door you have chosen and one additional door.

    At first, your chances of winning were 1/100, that means that with the door you have, you will win one out of hundred times. It is clear that making such a guess is hard, that's why the second door will most likely (99%) contain the car.

  • @Gytax0 How come? Could you illustrate that for me please?

  • @Gytax0 yes, i was about to post that

  • I like how the professor glances at his paper to see if he's a math genious or something. Maybe he just heard an explanation of the problem on Youtube?

  • This problem is so obvious and so easy to understand if you take not three, but say, a hundred of doors.

  • @ResidentMegamanX94

    yeah that's how it's supposed to work. It's only 1/3 to 2/3 if you know he always reveals a goat to you after you've selected a door. If they left something out or didn't explain it exactly right it wouldn't be a big deal, but they go out of their way to say that it works no matter what, which is what bugs me.

  • They did explain it wrong but that's not how it's supposed to work. The host will show a goat behind a door you didn't pick, and ask you EVERY time-whatever you originally picked-if you want to switch. Therefore, your odds increase from 1/3 to 2/3 because the fact that you know for a fact a door that has a goat behind it changes everything. Google does a better job of explaining it than me.

  • the way they explained it is totally wrong. It most definitely matters if the host knows what's behind the doors and he's doing his best to cheat you. With these dumbasses playing the game the host will never have to give away one car. If they pick a goat with their first pick then the host says 'game over you lose', if they pick the car the host reveals a goat and asks if they want to switch to the remaining goat and they switch everytime. What a bunch of suckers.
