- Two small problems:
-
- Given two random points within a sphere of unit radius, what is
- the expected straight-line distance between them ?
-
- Given a square sheet of paper, make three folds (nothing fancy, just a normal
- fold). At the end you will get a polygon. What is the maximum number of sides
- this polygon can have ? Can you generalize to n folds (assuming the paper has
- no thickness) ?
