I would like to train some recreational probability (Puzzles).

Does any of you know a good collection? Preferably with hints or answers.

I've been studying quite a bit of probability theory, but I don't suspect that will do me any real good.

Thanks in advance,

  • $\begingroup$ Typical textbook problems on probability are, in my experience, created to grow accustomed to theory or theorems. What I want are brain teasers I guess made out of curiosity or to tease the brain. I know the difference is delicate, but I hope you get the point. $\endgroup$

  • $\begingroup$ That book looks absolutely perfect! Thanks! If anyone of you know any more I bet those 40 problems will run out at some point :) $\endgroup$

There is a book, Fifty Challenging Problems in Probability With Solutions by Frederick Mosteller which is quite a good read. You can look up this blog which has a good list of puzzles worked out.

  • $\begingroup$ I've corrected the title and added a link to the book you mentioned. Check to make sure I got the right book. $\endgroup$

definitely agree that Mosteller's book is excellent. In case you exhaust that, there's also quite a few problems in the recreational vein in: Challenging Mathematical Problems with Elementary Solutions, Volume I: Combinatorial Analysis and Probability Theory.


Have just bought this myself actually for some recreational amusement.

Possibly the ultimate compendium of problems is Grimmett and Stirzaker's volme:


If you've done all of those, you've pretty much done it all!

Good luck.
