Two professors at a nearby university want to co-author a new textbook in either economics or statistics. they feel that if they write an economics book they have a 50% chance of placing it with a major publisher where it should ultimately sell about 40,000 copies. if they can’t get a major publisher to take it, then they feel they have an 80% chance of placing it with a smaller publisher, with sales of 30,000 copies. on the other hand if they write a statistics book, they feel they have a 40% chance of placing it with a major publisher, and it should result in ultimate sales of about 50,000 copies. if they can’t get a major publisher to take it, they feel they have a 50% chance of placing it with a smaller publisher, with ultimate sales of 35,000 copies. what is the probability that the statistics book would wind up being placed with a smaller publisher?
