The Monty Hall problem

The Monty Hall problem is a famous puzzle based on an American TV game show. Please read the following problem and answer the poll based upon what you think you should do.

“You are a contestant on a game show. To decide your prize, you are asked to choose one of three doors (door 1, 2 or 3). Behind one of the doors is a car (good prize). Behind two of the doors is a goat (bad prize).

You choose door 3. The game show host, who knows what is behind each door, opens door 1 to reveal a goat. He then gives you the option to change your original selection to door 2.”

Is it better to stick with door 3, change  your selection to door 2 or does it not matter?

  1. I’d stick with my original door.

    So whats the answer? I’m sure there is some big mathematical equation to find the answer but maths was never my strong point.

  2. Dear Michael:

    Hi, how are you doing?
    I am Albert S. Kim, an associate professor at the Department of Civil and Environmental Engineering, University of Hawaii at Manoa. Your blog site looks quite impressive.

    I am writing a book regarding Monte Carlo simulation and would like to use the Monty Hall dilemma as an interesting example. The Monty Hall game image in you blog site looks one that I want to use in my online book. Did you draw it? Then, can I use it in my book? Otherwise, could you let me know who owns the picture?

    Thank you so much.
    I am looking forward to hearing from you soon.


    • Thanks for visiting my blog.

      I sent an e-mail to the address I found for you online. In case that address was not correct I will also reply to you here.

      I’m sorry, but I don’t have the publication rights for the image I used. However, if you would like an image drawn in a similar style, I know someone who I am sure could do that for you. Just let me know.
