Someone pls calculate this lol
some rough physic logic that I can think:
1. By observing Maria's hand velocity while throwing the ball, Nagi get the approcimated ball's initial speed;
2. By converting it to radial motion she can approcimate the radial distance the ball will take.
3. 1/18 chances of a 360 degree circle is 20 degree for each number on red, so once Nagi get the approcimated radian where the ball will stop she can guess 1 of 3 slots that the ball will stop.
4. Maria's 100% aim for red color determine that the ball will only stop on red which mean the ball will either come to red on the middle of 3 (14), or two of the red on the side (14 & 9).
5. The rest is up to gravity, air resistance, and of course LUCK
