a question

[KarmaPolice]

My HR teacher asked us a question..she said its from a test that judges your IQ...she said its tricky but i dont think so.

You are at a game show. Three doors. You get to pick one. There is a duck behind one, a goat behind another and a cash prize behind the last one.

After you pick the first one they show you whats behind one of the other two doors, either the goat or the duck. You are given the chance to pick again. Which should you choose and why.

The door with the naked female behind it of course.

Here we go again...

If you change your initial selection, you are twice as likely to win the cash prize.

Are you sure you worded this correctly?

ugh...this isn't a test of IQ...its a test of knowledge of statistics...you change doors because the probability changes and gives you a greater chance at winning.

If you don't think it's hard, why not post your answer?

If this is a repost, can someone just say the answer?

You should always change your initial pick. You gain information after they tell you information about opened door. You have a higher probability of winning if you change your pick.

 

[illusion88]

There are three situtations

You picked a door with a duck
you picked a door with a goat
you picked a door with the money

Two out three situtations favor changing your answer. So unless you are feeling lucky, you change doors.

From an HR perspective you should pick applicants who stay the course. Switching midstream is a sign of weakness. You don't want weak employees do you? Hire switchers and the terrorists will have won.

 

[alyssa]

No, you don't change doors, you already chose the one with the money.

 

[eits]

why would i care? i would have already won the money...

you said that i picked a door and behind the other two was either a duck or goat, right? why would i care to deal with a either of them? the only reason why i'd be there in the first place would be for the 33% chance of winning the money.... and seeing how i won, i don't see why i'd need another chance.

if i had a gun to my head to choose between the duck and the goat, however, i'd pick the duck. a duck wouldn't be able to eat my stack of cash on the drive home.

So if you're doing something that isn't working staying the course is the best decision?
