Aspinner and 6 cards are shown below: a spinner with 3 equal sectors is shown in the figure. the colors green, blue, and red are marked on it. the arrow points at the green color. six cards are shown on the right side. the colors purple, green, red, yellow, blue, and pink are marked on them. jordan spins the spinner and picks up a card without looking. what is the probability that the spinner stops at green and a yellow card is selected? 1 over 36 1 over 18 1 over 6 1 over 3

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! )
