  1. Now let's say Monty picks a door and he picks door number 3
  2. as indicated by these bars over here.
  3. Put differently, because Monty picks door number 3
  4. all the other cases of picking door number 1 or 2
  5. now have 0 probability.
  6. Let me just cross them out.
  7. The only events that remain in the truth table are this one, this one, and this one.
  8. Here the true location of the car is door 1, door 2, and door 3.
  9. Unfortunately, these numbers don't add up to 1.
  10. They are a 1/3, 1/6, and 0.
  11. I want you to tell me what the true posterior probability is
  12. for the true location to be 1, 2, or 3.
  13. Please write those numbers down over here.
