“The projects were really helpful because they provided a way to see how all the things I learned work.”

#### Alejandro Giraldo Riveros

Environment Engineer & Data Analyst

## Project overview

In this project, you’ll assume the role of a data analyst at a medical institute assisting in the development of a mobile app to help lottery addicts make more informed decisions. You’ll use probability, combinatorics, and R programming skills to build the logic behind the app and calculate probabilities.

Working with real historical lottery data from Canada, you’ll write functions to find the probability of winning the big prize with a single ticket, check if a certain combination has occurred before, and calculate probabilities for any number of tickets or winning numbers. This project allows you to apply probability concepts to a real-world scenario while building your R programming portfolio.

Objective: Use probability, combinatorics, and R to develop an app that provides lottery addicts with a realistic understanding of their chances of winning, to help guide better decision making.

### Aaron Melton

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”

### Jessica Ko

#### Machine Learning Engineer at Twitter

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”

### Victoria E. Guzik

#### Associate Data Scientist at Callisto Media

“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”
