Factorials
Example: You have just been hired as book representative for Prentice Hall. On your first day, you must travel to seven schools to introduce yourself. How many different routes are possible?
The seven schools are different. Let’s call the schools A, B, C, D, E, F, and G. School A can be visited first, second, third, fourth, fifth, sixth, or seventh. So, we have seven choices for school A. We would then have six choices for school B, five choices for school C and so on. We can use the factorial to find our solution.
There
are
different
routes possible.
The total number of different routes that are possible can be computed using the factorial function.
