1. The problem statement, all variables and given/known data
In a lengthy manuscript, it is discovered that only 14% 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 typing error, At the most 2 typing errors, Two or more typing errors. Also compute the mean and variance of the number of typing errors per page.
2. Relevant equations
3. The attempt at a solution
I know for a Poisson distribution np=λ
the problem states that p=14% of pages with 0 errors, but don't I also need to know 'n' which would be the number of pages??? Anyone got a hint?
