Suppose that 22% of all arrows fired at a target by a specific archer hit the yellow ring (ie bullseye), 38% hit the red ring (around yellow ring), 39% hit the blue ring (around the red), the other 1% miss the entire target. Suppose this archer fires 30 arrows at the target, what is the approx. probability that 10 arrows hit the yellow ring, 15 arrows hit the red ring, 4 arrows hit the blue ring & the last arrow misses the target.
