This is, like, the oldest math riddle known to mankind. They dug this shit out of the pyramids in Egypt.

If you think you have a 50/50 chance of being right after they open one of the doors, press your ear to the monitor: THE CHANCE THAT YOU PICKED THE CORRECT DOOR THE FIRST TIME DOES NOT GO UP WHEN THEY TAKE THE THIRD DOOR AWAY. IT DOESN'T MATTER IF THEY REMOVE THE DOOR WITH A TACTICAL NUCLEAR STRIKE, YOU ARE STILL BETTER OFF CHANGING YOUR CHOICE.

If there are 1,000,000,000 doors and you select one then they take away 999,999,998 do you really think there is now a 50/50 chance that you picked the right door the first time? Of course not. There is still a one-in-a-billion chance that you picked the right door. There is also a 999,999,999-in-a-billion chance that the other door is the correct door.
