The factorial is useful for probability.
The factorial is a simple, understandable example of recursion, useful to
teach the concept; it is lacking only in that it is not very efficient.
But when you are first learning, I think concepts are more important than
efficiency.
Good examples of where recursion is actually useful are:
- ray tracing
- solving Towers of Hanoi
Not that these help explain the concept, though.
