Here's an example of a problem from an entirely different domain:

An error control coding scheme can correct up to 3 errors in the header of a
packet and up to one error in the body of a packet. A given message is
divided into four consecutive packets. Find all possible correctible
distributions of 6 errors among the four packets, treating the order of the
four packets as significant.
