Musicbanteran against TX

Switching improves the odds of winning. Let us assume you pick box 1. The number of the box you picked doesn't matter but it helps explain the reasoning. If you pick another box just swap 1 with the number you chose and you'd get the same result.
If the car is indeed box number 1 than you could reveal either 2 or 3. However if the car is in 2 you have to reveal 3 and if the car is in 3 you have to reveal 2. 2 out of 3 times you had to reveal a specific box, and in those cases the switch is the win. 2 out 3 times you should switch.

THIS IS RIDICULOUS!
OK, SO YOU HAVE 3 BOXES ON A TABLE. TWO BOXES CONTAIN VOUCHERS FOR DOG****, ONE BOX CONTAINS A VOUCHER FOR A MEDIEVAL CASTLE. (OBVIOUSLY YOU WANT THE FRICKIN MEDIEVAL CASTLE). SO YOU PICK A BOX AT RANDOM AND YOU CLUTCH IT TIGHTLY TO YOUR CHEST. YOU ARE THEN GIVEN THE OPTION TO OPEN UP ONE OF THE 2 BOXES ON THE TABLE, (THE TWO THAT YOU DIDN'T PICK), AND SEE WHAT'S INSIDE. OOH. WELL WHADD'YA KNOW, IT'S A VOUCHER FOR DOG****. SO NOW YOU'RE LEFT WTH JUST 2 UNOPENED BOXES. ONE UNOPENED BOX IS STILL ON THE TABLE AND ONE UNOPENED BOX IS BEING TIGHTLY CLUTCHED TO YOUR CHEST. ONE OF THESE BOXES CONTAINS THE CASTLE VOUCHER, AND THE OTHER CONTAINS THE DOG**** VOUCHER. ...HOW CAN THE ODDS OF PICKING THE MEDIEVAL CASTLE BOX BE ANYTHING OTHER THAN 1-IN-2, REGARDLESS OF ANY LAST MINUTE SWITCH?? a Last edited by RUPERT : 09-28-2008 at 08:08 PM.

Also for a strictly mathematical way to view it. When you pick the door at the start you have a 1/3 chance of being correct. Revealing one of the goats doesn't change the fact that you had a 2/3 chance of being wrong initially and therefore you still have a 2/3 chance of being correct by switching. The information doesn't change the odds.

Please admit that analogy is from 21 and I will be psychologically sound for the night.
