At a chinese buffet, there are five entree selections. If two entrees may be selected, how many ways may the plates be filled?

This would be the answer if the order the entrees are picked mattered. In this case it doesn't matter, so half of the 20 choices are duplicates. If the "tricky" possibility is allowed, the number of possible plates would rise from 10 to 15.
