This Excel file contains a number of different examples for the binomial theorem.  It includes the examples solved using the binomial equation, as well as examples solved using Pascal's triangle.  It includes examples that have a 50% likelihood, such as a coin flip, and examples that have a different likelihood.

There are a number of different plots of the probability mass function of the binomial distribution, as well as the cumulative distribution function.  For many of the examples, it is quite easy to plug in other numbers to see how the results change
