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

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
