limiting case of binomial
distribution is poisson distribution when n is large and p is small ---------------------------------------------- ----------------------------------------------- first start with the pdf of binomial distribution split up the nCx term take out the n from each factor collect all the (np) together eliminate p by changing everything to terms involving n then take the limit with n -> infinity you have to use the standard limit that [1-(k/n)]^n -->exp(-k) when n-->infinity see the following for some steps answer and some steps are given below ================ * * ================ ![]() ![]() other problems on applications of integration like area ,volume etc integration formulae problems on integration |
