## Homework Statement

Suppose a typographical errors committed by a typesetter occurs randomly. If that a book of 600 pages contains 600 such errors, calculate the probability by using Poisson's distribution.

i) that a page contains no errors

ii) that a page contains at least three errors

## Homework Equations

W(n) = [tex]\lambda[/tex]

^{n}e

^{-[tex]\lambda[/tex]}/ n!

## The Attempt at a Solution

I related [tex]\lambda[/tex] = Np, the mean number of errors and proceeded. I am supposed to get 0.37 for part i) of the problem but I didn't get it right. Any suggestion?
