When To Use Poisson Approximation of Binomial Distribution
This video covers the most important thing you need to know about these obscure problems: how to tell the difference between one of these vs a normal binomial probability problem. Also covered are the rules/technicalities you should know.
Examples Using Poisson Approximation of Binomial Distribution
This video covers the nitty gritty. Thankfully these problems are a lot easier to execute than they sound; once you figure out which problems to use this method on, the plugging-and-chugging isn't actually all that bad.
