I got that in a tech interview and hadn't seen it before. Dirty.

  In what context was the interview (ie type of position). I'm all for logical problem solving questions in interviews, even ones that can't be solved but are interesting to see how people tackle them. However this one doesn't seem to lend itself much to programming or true problem solving - just probability theorem. In other words, I'm not sure what useful info I'd get out of a candidate by asking them to work on this (other than their understanding of probability, which is not that useful for most programming jobs)
