Suppose that you are asked to approximate the number of unknown bugs that remain in a particular piece of software. You insert 100 bugs into the software and then have your QA team test the software. In testing, your team discovers 40 of the bugs that you inserted, along with 120 bugs that you did not insert.
a. Use these results to estimate the number of undiscovered bugs that remain in the program, assuming that you remove all of the discovered bugs as well as the 60 remaining bugs that you inserted.
b. Why might this test give inaccurate results?
