Question:medium

A typist claims that he prepares a typed page with typo errors of 1 per 10 pages. In a typing assignment of 40 pages, if the probability that the typo errors are at most 2 is p, then $e^2 p =$

Show Hint

For Poisson distribution problems, always scale the mean $\lambda$ linearly according to the size of the interval (here, the number of pages). If rate is $r$ per unit, for $n$ units, $\lambda = n \times r$.
