In Problems 57 - 60 , discuss the validity of each statement. If the statement is true, explain why. If not, give a counterexample. If m and n are positive integers and m ≠ n , then u m − v n is not factorable.

Two people proofread the same book. One person finds 100 errors while the second finds 60
errors. There are 20 errors common to both people. Assume that all errors are equally likely to
be found, and also that the discovery of an error by one person is independent to the discovery
of that error by the other person. Given these assumptions, roughly how many errors does the
book have?
Note that your answer will be an integer, so write your answer as such (i.e. your answer should
only contain digits. Do NOT include any other characters)
