15 years after ending my computer science and mathematical studies, I thought it was time for me to try out this little booklet. I think I made a good start, but soon enough the challenges became too hard for me to solve unguided. :-) Still, it served as a good reminder that statistics are not at all intuitive, which is especially useful to know in this day and age of big data (and COVID-19 related statistics all over the news).

The solutions were always clear enough however and the collection had no problem whatsoever keeping my interest level high. The reason I'm not 100% sure this publication deserves more stars is that, even though maths never gets old, the problems used to frame the maths do feel quite out of place in the 21st century. ( )

Mostly straight-forward questions. Some solutions are merely discussions instead of rigorous proofs. Concluding problems are, let's just say, a bitch. ( )

A very nice complementary problem book to any probability and statistics text. ( )
