i spent about 40 minutes on this section. It talks about Demos with Positive impact. There was a link called Calculator Bases Demos. In there there was a link called PLINKO, i thought it was a cool website because it shows how does probabilities work, another game that was similar to the Tv show the price is right. This really shows the student or people that wants to learn about probabilities and how to calculate them. this site is really quick and easy to learn.
