回答: good one, though don't know how you derived. 由 Amsel 于 2010-01-21, 19:45:12:

P(N)= [c(n,1)+3*c(n,2)+3*c(n,3)+c(n,4)]/[n^4]
where C(N,k) is the number of combinations.

I guess the volatility of the simulation might correctly reflects the large variation of the underline uniform distribution, not necessarily the Excel's problem.
