I spent about one hour reviewing this site. This site contains an excellent educational and fun information. I like this quote "In a world as crazy as this one, it ought to be easy to find something that happens solely by chance. It isn't". Also, i learned what is the probality? Intuitively, the mathematical theory of probability deals with patterns that occur in random events. Problability problem #9 Birthday Coincidence..... I found it to be interesting. I'm sure students and professor really enjoy this site because the quality of the material was great and well organized.
I think that first time users will find it easy to go through this website and try a variety of problems.
