What exactly are you doing when your finding patterns that occur in random events? Youre finding the probability of that event happening. Many students find probability very difficult to understand. Like other students, I was one of them. This site can clear many questions you may have about probability. It provides exercises to help students gain a better insight on how to answer problems. Some questions like Balls of Color, allow you to think the questions without the solution being revealed. It allows you to soak in the information and gives lots of room for critical thinking and application. The site is very well organized and is filled with quality problems to help study for exams. I found this site to be very helpful, and hope others enjoy it just as much as I did.
