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 is given as:

And, k = 2 errors.

Plugging in values in poisson distribution, we get

On solving, we get

= 0.0163  

Hence, the probability is 0.0163.
