In the second case, case B, we assume that the probability that the center of the needle falls in any subset of the circle is just the area of the subset divided by the total area of the circle. We again make the same assumptions ...

Draw equidistant, parallel lines inside the shoebox top. The distance between the lines should be the same as the length of the toothpicks. Make one of these for each of your groups. If you don't have the boxes, you can demonstrate the experiment by dropping the toothpicks on a tiled floor.
