This java applet allows you to '"compare the Poisson [distribution] with the Normal distribution with the same mean and variance."

West Virginia University, Department of Statistics, Intelligent Distributed Environemnt for Adaptive Learning resource demonstrating the Normal Approximation to the Binomial distribution.Requireme
This Java Applet demonstrates the Normal approximation to Binomial distribution. A "Begin" button on the left starts the applet. Browser is required to support Java 1.1+.
A description of the exponential distribution and its properties. Each property is stated, and a button shows the proof when clicked.
An expository page about the exponential distribution.
This video discusses the probability of getting an even number each time when rolling a standard fair die 3 times. The rolls are independent.
This is one in a series of lessons in probability on the Math Goodies site. Independence of events is described informally and then the multiplication rule is given.
This is a brief article on independence, and treats independent events, independent random variables, and independent sigma-algebras. The last topic is too advanced for an elementary course.
This site is an interactive text with links to simulations. The description of the game is followed by a series of 34 statements, including proofs and questions (answers are available).
Good statement of the problem with expectation and variance calculated. Several methods of bounding the expectation and variance are given as the number of coupons gets large.
