Hi All,  

I'd like to solve some math puzzles, especially in the context of probability theory, but I'm open to other areas too. The kind of problems that does not require much knowledge of mathematics, except, perhaps, for a basic background. 


I found this one helpful  

[http://www.amazon.com/Fifty-Challenging-Problems-Probability-Solutions/dp/0486653552](http://rads.stackoverflow.com/amzn/click/0486653552)


but I was wondering if you folks could recommend others. 


Thank you

[Problems and Snapshots from the World of Probability](http://books.google.ca/books?id=KCsSWFMq2u0C&printsec=frontcover&dq=blom+holst+sandell&source=bl&ots=R8Dj0_qoQg&sig=Evx4thEukrKZ0BZXfyVIzS-9TYI&hl=en&ei=CtqyTbKVJ460sAP_i53kCw&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBkQ6AEwAA#v=onepage&q&f=false) by Gunnar Blom, Lars Holst, and Dennis Sandell is a book that I like very much. Their problems are pretty challenging and assume a working knowledge of basic probability.
