| Dec 14, 2009 at 12:06 | comment | added | Gjergji Zaimi | Claudiu note that the i'th term in your sum (after division by i) gives the probability of there being AT LEAST i empty boxes and doesn't guarantee there being exactly i empty boxes. With your approach you'd have to subtract some terms ;) | |

| Dec 14, 2009 at 4:50 | comment | added | Claudiu | I was thinking of something along these lines, but doesn't it matter that the Xi variables are not independent? | |
