13) Two professors at a nearby university want to coauthor a new textbook in either
economics or statistics. They feel that if they write an economics book, they have a 50
percent chance of placing it with a major publisher, and it should ultimately sell about

an 80 percent chance of placing it with a smaller publisher, with ultimate sales of
30,000 copies. On the other hand, if they write a statistics book, they feel they have a 40
percent chance of placing it with a major publisher, and it should result in ultimate sales
of about 50,000 copies. If they cannot get a major publisher to take it, they feel they
have a 50 percent chance of placing it with a smaller publisher, with ultimate sales of
35,000 copies.
