The Monty Hall problem: beyond closed doors




Monty Hall(1921~)
The host of 'Let's Make a Deal'

The Monty Hall problem: beyond closed doors

Monty Hall problem is a probability puzzl. Puzzle Monty Hall problem was orginated the american television game show ‘Let’s Make a Deal’. It became famous in 1990, a reader’s letter quoted in Marilyn vos Savant’s “Ask Marilyn” column in Parade magazine.

 

 

   

Problem is as follows.

You’re given the choice of three doors. Behind one door is a car, behind the others, goats. First pick a door and them the host who knows where the car is opens another door which the goat behind. And he sats to you “You can change your choice. Do you want to switch?”. Here, is it to your advantage to switch your choice?
 

 Many people easy to misunderstand the solution is probability is same whether open it or not. Because the host open door and we pick one of the remainders. So we can think probability is 1/2 when we pick the door which the car behind. But that is not the anwser. You have to change choice. The probability of earning the car when switch choice is 2/3.

 Here is the solution.
 The probability of you choose the door the goat behind is 2/3 and then host show you another door the goat behind. So if you switch your choice you can get a car. But if you choose the door the car behind that probability is 1/3 and switch, you can’t get a car. And to conclusion you need to change your choice.

'Ask Marilyn'

 

 

 When Vos Savant dealed with this problem, many readers of her column refused to believe switching is beneficial despite her explanation. Interestingly, approximately 10,000 readers wrote to magazine, most of them claiming she was wrong and 1,000 people among them were PhDs.

 This is conditional probability puzzle. Many the other puzzle about conditional probability is interesting that we can easily confused. So if you understand some conditional probability puzzle, you can have another  viewpoint when you meet the problem like this.

Haiku

Last week, our class created haiku, a kind of Japanese poetry. Haiku are characterized by their brevity and emphasis on simple ideas, often evoking nature or time. Although they are not strictly limited to the oft-taught 5-7-5 or 3-5-3 syllable pattern, our students really enjoyed trying to figure out syllable counts for English words, an aspect of the language they'd never before had to consider. By reading our students' haiku, you can tell what inspires them most: daily life, relationships, happiness, and fried chicken. Here are just a few:

good day

Blackout Poetry

Recently, our class created Blackout Poetry, inspired by the work of Austin Kleon. Using old TIME magazines from the school library, we found articles that inspired us and then got to work defacing them in order to create art.

First, look for words and phrases that jump out at you. Then, circle other words, or parts of words, to create meaning out of the rest of the text. Lastly, use a black marker to black out everything else. All that's left is your unique poem!

The poems we created are now on display on the 3rd floor of the main school building. Those who see them are very impressed.

Here are some of our pieces. Enjoy!
