In a lengthy manuscript, it is discovered that only $13.5$ percent of the pages contain no typing errors. If we assume that the number of errors per page is a random variable with a Poisson distribution, find the percentage of pages that have exactly one error.
Added by John K.
Step 1
We know that the percentage of pages with no typing errors is $13.5\%$. In terms of probability, this means that the probability of a page having zero errors is $P(X=0) = 0.135$. Show more…

Independently on each page, the number of typing errors per page in the final draft of a thesis has a Poisson distribution with average 0.05. Find the probability that a randomly chosen page will contain no typing error.

Suppose that the number of typographical errors on a single page of a book has a Poisson distribution with parameter μ = 1. Calculate the probability that there is at least one error on a given page.
