An animal is randomly selected from a group consisting of 5 cats, 11 dogs, and 14 rabbits. find the probability of the outcome. enter your answer as a decimal, rounded to the nearest hundredth. at a soccer camp, a group of soccer players randomly drew numbers from 1 to 44 to determine which practice squad they would be on. what is the probability that the first player to chose a number picked a number less than 12? write answer as a decimal rounded to the nearest hundredth. ***probability*** fast

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! )
