Tanisha hit 40 golf shots and measured the distance of each shot. her results are shown below. 16 14 12 10 8 6 4 2 0 170–179 180–189 190–199 200–209 golf-shot distance number of shots distance (yards) what is the experimental probability that tanisha hits a shot that is in the 180–189 yard range? show your math! a. 11/40 b. 2/5 c. 5/8 d. 29/40

the clb she uses is a driver, so its a 2/5 chance she hits a 180-189 yard shot

step-by-step explanation:

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! )
