“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.”

Introduction to Probability in R

Enroll For Free

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.

Key skills

Estimating theoretical and empirical probabilities
Understanding the fundamental rules of probability
Calculating combinations and permutations

Aaron Melton

Business Analyst at Aditi Consulting

“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!”
