• Friday Q&A: any smart folks out there?
    Posted by on Mar 12th, 2010

    Havn’t had one of these in a while and my mate Duncan is convinced he has the answer correct:

    The following problem was presented in a column in a magazine by Marilyn vos Savant (yes that’s where the word Savant comes from since she had an IQ of 190) and it completely stumped 92% of people who answered..including maths professors who argued that she was incorrect.

    Here’s the question:

    Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the other two doors are goats. You are asked to pick a door that is not opened. The host, who knows what’s behind the doors, opens one of the other doors and reveals a goat. He then says to you that you have one last chance to change your mind and pick the other unopened door. What should you do?

    See now my buddy Duncan reckons that its 50:50 and he may as well stick with his initial choice.

    But what if i told you that Marilyn vos Savant said you should ALWAYS change you initial choice and take the other door?

    Noddy badge if you tell me why without looking below for the answers.

    Wrap your tiny brain around that one.
