...let me say that DJT failing a college-level Statistics class is about as surprising as the sun rising in the east. It's a challenging subject, even at intro level, and not only mathematically. Proper interpretation of statistical data is a Philosophy of Science matter, and it's not simple stuff, although also not an aspect that gets a lot of examination until a 300-level (or so) course. A nepo dullard like Don wouldn't stand a chance.
