Alright, that makes sense to me. If instead of doing i<j we just take i=/=j, (forgoing the 2 in front of the summation), I believe there are k^2-k possibilities for i even j odd, k^2-k possibilities for i odd j even, and 2k^2 possibilities for j and i both odd/even. This leaves 4k^2-2k...

Hi Ray, Thanks for the help! Sorry about the delayed response - some things came up. It seems to me like the Pr{Nobody hits blue bucket i} would be: (2/3k)^m*(1/3k)^w, where m is the number of men and w is the number of women (pink bucket is the same, with m and w swapped). Hence, Pr{Blue...
