The average number of typographical errors (typo) found in a typed manuscript is 0.3 per page. Suppose that the entire manuscript has 180 pages and the number of typographical errors on each page is independent of the number of typos on the next. Suppose that the first chapter of manuscript has 12 pages. Answer the following questions.

a) What probability distribution is most appropriate for calculating the probability of a given number of typos? Give the distribution and its parameters. (1 point)

b) What is the probability that there are 4 or fewer typos in chapter one of the manuscript? (2 points)

c) Calculate the probability that a randomly selected page from the manuscript has at least one typo? (1points)

d) Let X be the number of pages in in chapter 1 with at least one typo. Give the distribution of X and its parameters. (1 point)

e) What is the probability that less than two pages in chapter one have at least one typo? (2 points)
