Abook contains 400 pages. if their are 80 typing errors randomly distributed throughout the book, use the poisson distribution to determine the probability that a page contains exactly 2 errors

Using the Poisson distribution to determine the probability that a page contains exactly 2 errors is 0.0163

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.

The Poisson distribution formula is given as:

Where, is event rate of distribution. For observing k events.

And, k = 2 errors.

Hence, the probability is 0.0163
