I think you're describing the number 0.888... where the 8s will keep
going forever and never end.

Now, I've been around a long time, and worked a lot of math, but
I never knew how to make a fraction out of repeating decimal until
just a short time ago. That's exactly what we need here. Here's
the trick:

-- You have a decimal, with a set of digits ... 1 or 2 or 3 or however many ...
that repeat.

-- Take one complete set of the digits that repeat. Write them
on top of a fraction.

-- On the bottom of the fraction, write the same number of nines
as however many digits are on top.

-- THERE's your fraction that's equivalent to the repeating decimal !
You can go ahead and simplify it if it's possible and you feel like it.

In this problem, the repeating part is only one digit ... the 8 .

Write 8 on top of the fraction. Then write a single 9 on the bottom.

There's your equivalent fraction.
0.888...repeating is equal to 8/9 .

the answer is 200

step-by-step explanation:

this is a problem about poisson probabilities. i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.

here's how you can see a poisson distribution coming. when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution. this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot. there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything. the form of the distribution is

probability of n chips = {[e^(-x)]*(x^n)} / (n! )
