To estimate the number of errors in a new piece of software by applying the errorseeding approach, a programmer puts 15 deliberate (seeded) faults into the program.

A second programmer then tests the program and finds 35 errors, 12 of which are

confirmed by the first programmer to be seeded errors. Estimate the original number

of faults in the program (i.e., excluding the seeded errors).
