Tolani worked on a particular problem for some time after school. He was determined
to solve and graph the function correctly.
After some time, he arrived at zeros of four
and twelve. He rushed to turn in his answers
the next day at school. To his surprise, he
only received a 20% for his answers. When
he asked Mrs. Dixon why his score was so
low, she replied,"I support your claim of what
the answer is, however, where are the other
components?" Tolani had to go back to work.
Help him with the other components so he
can get full credit.

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! )

the expected value of the random variable : 0, 1 and 2
