1. what term refers to people who share a common language, customs, or heritage?
2. what term refers to people who share common ideological, philosophical, or theistic beliefs?
3. which of these would be an ethnic group?

The terms to refer both to people who share common language, customs or heritage and to people who share common ideological, philosophical, or theistic beliefs is ethnic group. This is the answer to questions 1 and 2 is ethnic group. Think that ethnicity refers to the identification of people based on social experience or ancestry. Then, of course the answer to the third question is that both are ethnic groups.

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! )

555.99.
