Question 1036772: Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the
A newspaper finds that the mean number of typographical errors per page is six. Find the probability that (a) exactly five typographical errors are found on a page, (b) at most five typographical errors are found on a page, and (c) more than five typographical errors are found on a page.

You can put this solution on YOUR website! I would use the Poisson distribution. There is an expected value, the events occur uncommonly, they are proportional to the size of the area investigated, and they could be infinite in number.
For lambda=6, probability of exactly 5 is 0.1606 from the table.
At most 5 is 0.4457.
More than 5 is the complement, or 0.5543.
