Often in physics we won't be able to predict motion of a bunch of objects exactly and so we resort to statistical methods. An example of a statistical approach is the resulting profile of a bunch of disks dropped through a series of pegs. As each disk falls it encounters pegs and bounces to the left or the right of the peg with equal probability.
If we dropped many disks from the top through the pegs, what is the ratio of the number of disks in bin 6 to the number of disks in bin 4?
