http://en.lichess.org/editor?fen=1k6/8/1KB1N3/3N4/8/8/8/4Bq2_w_-_-_0_1A very rare endgame (0.001% chance it will occur) where 4 minor pieces duel an recently promoted queen.
play this against the machine
Can the four minor pieces win against a queen? Well, in this instance, it's a mate in 3 (2 if the queen doesn't block).
In general, 4 minors should win against a queen - barring passed pawns.
I suspect it depends on the minor pieces! I suspect that both 4N vs Q and 4B vs Q (bishops all on the same color) are drawn.
I have created just this, to show the value of material
