Assuming that the arrow is shot at the middle of the central can, calculate the probability that the can that the arrow hits, will be the central can. The uncertainty in the position of the cans is small and not important but the uncertainty in the position of the arrow is large at 5Å. Since any can within 2.5Å of the center can be hit, the 2 cans on either side of the central can may be hit, making the probability only 1 out of 5....
