⚠️ CAUTION: DO NOT SOLELY RELY ON MY NOTES. THERE MIGHT BE TYPOS AND MISTAKES. ALWAYS TAKE YOUR NOTES!

✔️ The goal of this week is to familiarize yourselves with basic probability theory and distributions.

Here are some key points:

• Probability is indicated either as 0 (zero, never happens) or 1 (one, always happens).
• Percentages and probabilities are almost the same.
• Joint probability is the probability of two or more things occuring together
• Statistical independence indicates that the condition has no impact on the probability
• Independence occurs when one of event has no effect on the other event. Statistical independence and mutual exclusivity are two important concepts we are learning today.

Some recommendations:

• Get familiarize with probability theory, set notation, and probability types.
• Learn to define p-value correctly!
• If you need extra help in probability, maybe this post can help 🧐
