Abag contains eleven red marbles, seven blue marbles, nine green marbles, and thirteen yellow marbles. which of the following statements is not true? the theoretical probability of selecting a red marble from the bag is 27.5%. the odds of selecting a yellow marble from the bag are 13 to 27. the theoretical probability of selecting a blue or green marble from the bag is . the odds of selecting a red or blue marble are .

In total there are 40 marbles because 11+7+9+13=40

There are 7 Blue marbles, so

P(blue)=7/40

\

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! )
