you are a participant in a TV game show, and you are shown three doors. there is a car behind one door, and one goat each in the other two doors.
you pick door #1.
before opening all the doors to reveal what you won, the host of the TV show just opens door #2. there is a goat behind door #2. the host of the TV show then turns to you and asks - "do you want to stick with door #1 or switch to door #3?"
would you stick to your original choice or switch?
when trekking or climbing mountains, finding a toilet with a door is a luxury. finding a toilet with no door is normal. #bcc
