  1. Hi everyone. I'm having a little trouble with my Math IA., I would like to do the topic "The Mathematics behind Medical Testing", where I would speak about false positives / false negatives and the probability of getting them. However, I don't know where to get data from. Am I supposed to make up a hypothetical situation / disease and then make fake numbers for it ? Is that even allowed..? I would be using conditional probability to find the probability of a student testing positive for the XYZ disease, actually having the disease. I would be using the conditional probability
