3.(09.01 MC) Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10.
What are Henry's chances of getting a second turn when he rolls the number cubes? (2 points)

Step-by-step explanation:

The even numbers less than 10 are

2  which can only be done 1 way: when you roll snake eyes.

4  can be done 3 ways (2,2) (3,1) and (1, 3)

6 can be done 5 ways (2,4) (4,2) (5,1) (1,5) and (3,3)

8 can be done 5 ways (4,4) (2,6)(6,2)(5,3) and (3, 5)

There are 36 ways of throwing the number cubes.

We have a total of 5 + 5 + 3 + 1 = 14 ways

The answer you want is

14/36 = 7 / 18 = 0.389

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! )

answer is x<
