Probability helps you make smarter decisions—from judging risks to interpreting data. In this path, you’ll learn to calculate chances, estimate probabilities from experiments, build useful models, and solve multi-stage problems with confidence using only basic arithmetic.
You'll learn what probability means, explore how to describe chance processes with outcomes and sample spaces, and calculate the probability of simple events using the equally-likely-outcomes method.
You'll discover how to estimate probability from real data by computing relative frequencies, see why small samples can be misleading, and observe how estimates stabilize as you collect more trials.
You'll learn to build formal probability models for chance processes — both with and without equally likely outcomes — use models to predict expected frequencies, and evaluate models by comparing predictions to observed data.
You'll extend probability to events with two or more stages by using organized lists, tables, tree diagrams, and simulation to find and interpret compound event probabilities.
I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
