  1. Let's start with door 3, and here the answer is 0.
  2. You already saw when the curtain was lifted that there is no car.
  3. How about door 1, and that is a really tricky question.
  4. For reasons that I'll explain in a minute,
  5. it's actually 2/3 or 0.667. It's entirely non-intuitive.
  6. Given that this is the case, what do you think is the number for door 2?
  7. Of course, this is 1 - 2.3, which gives me 1/3 or 0.333.
