Consider the following scenario.
julie is 300 feet away from her friend’s front porch and observes, "someone is sitting on the porch."
given that she did not specify otherwise, we would assume that the someone julie thinks she sees is a human. we cannot guarantee that julie’s observational statement is true. it could be that julie’s friend has something on the porch that merely looks like a human from far away. julie assumes she is correct and moves closer to see if she can figure out who it is. as she nears the porch, she declares, "ah, it is our friend, john berry."

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! )

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
