Applications of Probability Rules

This video was produced to answer the following task: "You want to know how probable it is for you to meet a student from a different field of study and expand your horizons in a bar you and your Cognitive Science friend like to visit. However, you feel it would be awkward to walk around the Schloss and ask strangers where they spend their nights. So instead you decide to infer this using the sum and product rule of probability. A very representative inquiry among your Coxi-friends tells you that about 70% of all Coxis seem to frequent the bar. Since the bar is rather small, you know that in total (at most) 6% of all students frequent the bar. Let's assume that there are roughly 650 enrolled Cognitive Science students and a total of about 13000 enrolled students at Osnabrück University. (a) What's the joint probability that a random student is a Coxi and frequents your favourite bar? (b) What's the joint probability that a random student is not a Coxi and frequents your favourite bar? (c) What's the conditional probability that, if they are not a Coxi, they frequent you favourite bar? (d) What's the probability at least one of the first ten people you see at the bar is not a Cognitive Science student?" In the winter semester 2020/21, the Neuroinformatics tutors, like many other teams around the globe, were challenged with the task to adapt the lecture to an online format. Instead of weekly homework assignments and a final exam, the students were asked to produce videos that would help their peers in their studies at home. The videos cover a range of topics and themes. Some discuss concepts, some explain mathematical proofs or exercises, and others explore applications of methods and concepts in (cognitive science) research. The class and their hard work exceeded the expectations we tutors had, therefore we want to share some of the brilliant work. This particular video was produced by Lisa, Sascha, and Luca.
