“I liked Dataquest because I can control how fast I do the problems. The small scale projects help to make the transition from concepts to the real thing.”

## Course overview

In this course, you’ll learn the difference between theoretical and experimental probability, and you’ll calculate the probabilities for a variety of different events. You’ll also learn the number of permutations and combinations possible in experiment outcomes.
You’ll apply this knowledge in a guided project to build the logic for a mobile app that estimates lottery odds.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser.

### 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!”
