simply the best book on probability i've read so far. unlike other math sections, probability is considered a difficult one. heck Leibniz sucks in probability. when it comes to probablity, one needs to develop intuition in order to master it, just applying formulas just wont work as each problem is different. this books strives to develop that intuition in the reader. If you are just like me who have tries most of the books and still dont understand probability better, give this book a shot, you will understand the subject much much better!
