## demoivre-laplace approximation

i was studying bernoulli trials and there i encountered two approximations ...stirling approximation and demoivre laplace approimation ..now i have understood the stirling approximation and its use and also have seen a sloppy proof of it from wikipedia ...in the book im reading it says that from stirling approx and a few series expansion we can prove the demoivre laplace approximation ...how to do that ...and also applications of it in probability ....thankyou in advance
