A.K.A Gatekeeper
I love food, don't deprive me of it.
I'm not Princess, I'm Queen
I can be quite grumpy and when I am, I hide here, my dungeon for reflections, ramblings and ranting.
Whatever I write are opinions, and may not be the whole truth. Do not read it like the Gospel.
I hate as vehemently as I love
I already know I'm crazy, be my friend, it's safer
Different is not bad, just not the same as the rest
If you don't like me, it's probably mutual
But I'm nice, really :p

| Suppose you're on a game show and you're given the choice of three doors. Behind one door is a car; behind the others, goats. The car and the goats were placed randomly behind the doors before the show. The rules of the game show are as follows: After you have chosen a door, the door remains closed for the time being. The game show host, Monty Hall, who knows what is behind the doors, now has to open one of the two remaining doors, and the door he opens must have a goat behind it. If both remaining doors have goats behind them, he chooses one randomly. After Monty Hall opens a door with a goat, he will ask you to decide whether you want to stay with your first choice or to switch to the last remaining door. Imagine that you chose Door 1 and the host opens Door 3, which has a goat. He then asks you "Do you want to switch to Door Number 2?" Is it to your advantage to change your choice? |
Ahh, this REALLY got their attention. Everyone was like debating about this. First, they were gathered around me screaming that it shouldn't matter if the player decides to switch or not because the chances of getting the car is 50/50.
But I'm telling you it's not 50/50. You can read why here.
The commotion got the attention of those who just came in and didn't know what was going on. So one of the original group had to leave the mob to explain what was going on. Then, they had their own debate at another corner of the room which I found pretty funny.
Anyways, Marilyn Vos Savant, the one who supposedly has the highest IQ in the world said we should switch since switching would give us a 2/3 chance of winning the car while sticking with our choice would only give us a 1/3 chance.
If you still don't believe her after reading the wikipedia article, you can play the Monty hall game here.
To be really honest, I didn't get her logic initially, putting me in the category of "People with normal intelligence." But I found her logic very interesting and decided to read on. I pondered upon the solution for an hour or so before attaining enlightenment.
I think the crtical condition here is that the host HAS TO KNOW WHERE THE CAR IS. If he doesn't then yes, it doesn't matter if we switch or not.
Hahaha I honestly feel quite smart now! Oh and if you wanna ask your friends this question, be prepared to face really violent objections. People cannot seem to accept that they've got only normal IQ.
