# Curiz threw darts at a dartboard. 40% of his darts hit the bull's-eye. How many darts did NOT hit the bull,s-eye?

Well, 60% of his darts did not hit the bulls-eye..........
So if Curiz threw 30 darts (i.e. $10 \times 3$ darts), 12 darts hit the bull, which is a not unimpressive accuracy. He should have been aiming for the treble $17 , 18 , 19 , 20$ if he wants to be a pro.
