This game board is made up of concentric circles. The center circle has a diameter of 4 inches and is worth 100 points. Each successive ring has a radius 2 inches greater than the ring before. 2nd ring is worth 80 points, and last ring is worth 60 points. Find the probability of hitting the 2nd ring and scoring 80 points.
