routes depend on connecting roads, but there are
8C3 = 56 ways to pick 3 from 8 items.
There are, however, 8P3 = 336 different ways those 3 items can be arranged.
The idea of 2.67 different routes is meaningless. What is a fraction of a route?
With a short time remaining in the day, a fedEx driver has time to make deliveries at three locations among the eight locations remaining. How many different routes are possible? did i do it right 8/3= 2.67
