tl;dr

Simple tool written in Python 3 to explore the Monty Hall Problem and its solution.

Installation

git clone https://github.com/RagingTiger/MontyHallProblem.git && cd MontyHallProblem
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

Introduction

The version of the Monty Hall Problem presented here is the standard version with the standard assumptions:

• 1 The host must always open doors not picked by the contestant.
• 2 The host must always open doors that reveal goats and never the car.
• 3 The host must always offer the chance to switch between the originally chosen door and the remaining closed door.

Usage

The command line interface portion of this module uses the fire library, which generates the below documentation by running python montyhall.py as follows:

$ python montyhall.py
NAME
montyhall.py - A class with various methods for simulating the Monty Hall
problem.
SYNOPSIS
montyhall.py COMMAND
DESCRIPTION
A class with various methods for simulating the Monty Hall problem.
COMMANDS
COMMAND is one of the following:
experiment
Run multiple games of Monty Hall problem
lmad
Interactive version of Monty Hall problem (i.e. Lets Make A Deal).
predict
Calculate the predicted probabilities of no switch vs. switch.
simulate
Non-interactive version of Monty Hall problem

To find out more about any of the COMMANDS shown above simply run the help flag --help after the command. For example to learn about the predict command:

$ python montyhall.py predict --help
NAME
montyhall.py predict - Calculate the predicted probabilities of no switch vs. switch.
SYNOPSIS
montyhall.py predict NDOORS
DESCRIPTION
Calculate the predicted probabilities of no switch vs. switch.
POSITIONAL ARGUMENTS
NDOORS
The number of doors to use.
NOTES
You can also use flags syntax for POSITIONAL ARGUMENTS
