Learning outcomes

By the end of the course, you will be able to


Topic Key take-away points Lecture notes
1. What is probability? i) When it comes to probabilities, we do not trust our gut, we trust the formulas; ii) We estimate population probabilities from observed frequencies in samples; iii) The chosen sample is very important notes
2. How do we combine probabilities? i) Product rule: we can calculate the probability of simultaneous events when they are independent; ii) Addition rule: we can calculate the probability of different disjoint events notes
3. How do we update probabilities when new information is available? i) The conditional probability allows us to update a probability with new information; ii) Very important not to confuse the conditioning event as probabilities would change notes
