3. If a publisher of nontechnical books takes great pains to ensure that its books are free of typographical errors, so that the probability of any given page containing at least one such error is 0.005 and errors are independent from page to page. What is the probability that one of its 400-page novel will contain at most four pages with errors? (4 pts)

Step 1
Since we are dealing with a fixed number of trials (100 pages), each with two possible outcomes (error or no error), and the probability of error is constant, this is a binomial distribution problem. Show more…

A first draft of a 200-page manuscript has 16 typos that are spread randomly across the pages. Assume the number of typos per page follows the Poisson distribution. Complete parts a through d. a. What is the probability that there is exactly one typo in the first 20 pages? 0.3230 (Round to four decimal places as needed.) b. What is the probability that there is exactly one typo in the first 40 pages? (Round to four decimal places as needed.)

In the first draft of a book on probability theory, there are an average of 15 spelling errors per page. Suppose that the number of errors per page follows a Poisson distribution. What is the probability of having no errors on a page?
