The book Code Complete by Steve McDonnell estimates that there are 15 to 50 errors per 1,000 lines of delivered code for computer programs. Assume that for a particular software package, the error rate is 20 per 1,000 lines of code and that the number of errors per 1,000 lines of code follows a Poisson distribution.  What is the probability of there being exactly 29 errors in 1,000 lines of code? (Round your answer to four decimal places.) What is the probability of more than three errors in 100 lines of code? (Round your answer to four decimal places.)
