Please help! i really need this

1/6

Step-by-step explanation:

1/6th is the answer. The cube has sides that are labeled 1 to 6. Since 4 is one number that is a possibility and there are 6 possibilities that the cube may roll another number.  He has 1/6th of a chance that the number lands on 4.

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! )

c - they will have the same distribution

this is the only one that could make sense. : )
