There are four cars entered into a pinewood derby race. in how many different orders can they cross the finish line, assuming there are no ties?

This is a problem of fundamental counting principle. In a sequence of events, the total possible number of ways all events can performed is the product of the possible number of ways each individual event can be performed.
