# Monty Hall Problem
a node package that models the [Monty Hall Problem](https://www.wikiwand.com/en/Monty_Hall_problem) from probability
[](https://travis-ci.org/rauljordan/montyhall.js)
## The 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 others, goats. You pick a door, say No. 1, and the host, who knows what's
> behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do
> you want to pick door No. 2?" Is it to your advantage to switch your choice?
Taken from the wikipedia article: The Monty Hall problem is a brain teaser, in the form of a probability puzzle (Gruber, Krauss and others), loosely based on the American television game show Let's Make a Deal and named after its original host, Monty Hall. The problem was originally posed in a letter by Steve Selvin to the American Statistician in 1975 (Selvin 1975a), (Selvin 1975b). It became famous as a question from a reader's letter quoted in Marilyn vos Savant's "Ask Marilyn" column in Parade magazine in 1990 (vos Savant 1990a):
## Installing Monty Hall
```sh
$ npm install montyhall
```
## Methods
```javascript
/**
* @param numberOfDoors {Integer} - The number of doors you want to simulate
* @param willSwitch {Boolean} - Whether or not you decide to switch
* @param numberOfIterations (Integer) - Amount of times you want to simulate it
*/
montyhall.simulateIterations(numberOfDoors, willSwitch, numberOfIterations)
```
```sh
$ var montyhall = require('montyhall')
$ montyhall.simulateIterations(3, true, 100)
$ With 100 iterations and by switching
With 3 doors
You succeeded 67 times
With a success percentage of 67%
```
```javascript
/**
* @param numberOfDoors {Integer} - The number of doors you want to simulate
* @param willSwitch {Boolean} - Whether or not you decide to switch
* @return {Boolean} - Whether or not you succeeded
*/
montyhall.simulate(numberOfDoors, willSwitch)
```
```sh
$ var montyhall = require('montyhall')
$ montyhall.simulate(3, true)
$ true
```
