A queen, a rook and a bishop are randomly placed on distinct squares of an ordinary chessboard. Find the probability that:.
(i) The queen is under attack from either the bishop or the rook.
(ii) The bishop is neither under attack from the queen, nor under attack from the rook.

(In reply to computer aided solution by Charlie)

Just out of curiosity, does this take into account the bishop blocking the rook, or the rook blocking the bishop in part 1, or the rook blocking the queen in part 2?
