1. The problem statement, all variables and given/known data w!/(w-n)! = number of ways of distributing n* distinguishable particles in w distinguishable states w = number of distinguishable states n = number of indistinguishable particles How many ways are there to put 2 particles in 100 boxes, with no particles sharing a box. 2. Relevant equations ln(n!) = nln(n) - n 3. The attempt at a solution I get ln(n!) = 100ln(100) - 100 = 360.5 and ln(98!) = 98ln(98) - 98 = 351.3 I need to raise both of those numbers to e to get the final answer, but my calculator can't do that. The final answer is a relatively small answer that a calculator can handle, but getting to that answer is impossible unless you do some intermediate step. That step involves doing something with these numbers before I raise them to e. I can't figure out what that step is. Thanks.
