On a farm, the farmer decides to give pizza to her 18 ducks as a special treat. she orders 3 pizzas, and the total price is $26.28. what is the unit price of each pizza? 1 $4.38 2 $8.76 3 $23.28 4 $78.84

Answer

8.76 is the price of each pizza

Step by step solution

26.28 divided by 3 = 8.76

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! )
