SUMMARY
The discussion focuses on approximating the binomial distribution to the Poisson distribution, specifically through the expression N!/(N-n)!=N^n. The user attempts to simplify the factorial expression using various methods but finds it complicated. They mention the Stirling formula and its potential relevance to the approximation process. Ultimately, they seek clarification on the selective use of approximations and the application of the Stirling formula in this context.
