...ually exclusive events, and a "remainder" class with a probability p0=1-p1-p2-....-pk, and need to calculate, for a given number of trials t>=k, the combined probability that each of the classes 1...k contains at least 1 "event" (the remainder class may be empty). To me this reaks of a sum of multinomial distributions, and indeed, I can readily calculate the correct answer for small figures t,k using a small R program. However, in my typical experiment, k ranges from ~20-60 and t from ~40-100, and having to calculate these for about 6e9 experiments, a quick calculation on...
