Students are wondering what is the data for assignment, hint #1 is very bad english etc. So we have to fight against poorly made example, we cannot show our LLM skills.
Hopefully someone who has done this course, get informed and he/she can fix the notebook, give some real hints, what means randomness here, And why it just takes randomply Male/Female, even firstname is from Male.
