Probability of Exactly 0 Errors

a. A book of 450 pages contains 450 random misprint error(s). What is the probability of exactly 0 errors on a randomly selected page?
b. What is the probability of at least 3 error(s) on any one page?
c. What is the probability of between 1 and 4 (inclusive) random misprint error on any one page? Express you answer using 3 significant digits.

Solution Preview

a) Exactly one error on a randomly selected page
lambda = 450/ 450
= 1

Poisson formula

e^(-lambda) * lambda^x
P(X) = ...

Solution Summary

This solution uses the poisson formula and includes calculations and answers.
