Using the Poisson distribution to determine the probability that a page contains exactly 2 errors is 0.0163
<h3><u>Solution:</u></h3>
Given that, a book contains 400 pages.
There are 80 typing errors randomly distributed throughout the book,
We have to use the Poisson distribution to determine the probability that a page contains exactly 2 errors.
<em><u>The Poisson distribution formula is given as:</u></em>
Where, is event rate of distribution. For observing k events.
And, k = 2 errors.
Hence, the probability is 0.0163
