English professors at a certain university must compile a reading list that consists of 1 play, two short stories, and one novel (order doesn't matter). The department has approved 5 plays, 5 short stories, and 5 novels from which professors can choose.
How many reading lists can be created?
number of plays = 5
two short stories from 5 = 5C2 = 10
number of novels = 5
Use the Fundamental Counting Principle:
total = 5x10x5 = 250 reading lists
