Floyd is an aspiring music artist. He has a record contract that pays him a base rate of $ 200 $200dollar sign, 200 a month and an additional $ 12 $12dollar sign, 12 for each album that he sells. Last month he earned a total of $ 644 $644dollar sign, 644.

37 albums

Step-by-step explanation:

Question wants to know the number of albums sold last month.

He is paid $200 base rate every month so we need to remove this to find out the total he made from album sales:

= 644 - 200

= $444

If he made $444 from album sales when he got $12 per album, the total number of albums sold is:

= 444 / 12

= 37 albums

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! )
