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.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
