Older Life is Savage readers will remember that every Friday i did a post that presented a puzzle or a paradox with a solution that is not as easy as it looks. I think it’s time to bring back some of those old questions since there are so many new readers and followers now.
See if you can figure this puppy out.
The following problem was presented in a column in a magazine by Marilyn vos Savant (yes that’s where the word Savant comes from) and it completely stumped 92% of people who answered..including maths professors and fellow clever folks.
The Monty Hall Problem:
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 if you want. What should you do?
See now my buddy Duncan reckons that its 50:50 and he may as well stick with his initial choice.
Wrap your brain around that one. What do you think?
The solution is after the jump.
What if i told you that Marilyn vos Savant said you should ALWAYS change you initial choice and take the other door? Because 2 times out of 3 you will get the car if you change. If you are one of those folks that don’t bother trying to work it out then click the links below for the solutions.
