Two hundred fifty-six TCC faculty members were surveyed regarding their plans for the upcoming weekend. The results were as follows: 152 plan to grade papers 99 plan to attend a football game 114 plan to do household chores 33 plan to grade papers and attend a football game 75 plan to grade papers and do household chores 36 plan to attend a football game and do household chores 15 plan to grade papers, attend a football game, and do household chores

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! )

how am i supposed to answer

step-by-step explanation:

it has changed from the width and the height.

step-by-step explanation:

one set of data has more variation than the other. hope this !
