What is the probability that a randomly selected airline ticket is for an international flight?

express the probability as a percent rounded to the nearest tenth of a percent.

enter your answer in the box.

a survey was done where males and females were asked if they would prefer to eat chicken or steak. the results of the survey are shown in the two-way frequency table.

chicken steak
male 0.236 0.218
female 0.311 0.235

what percent of the males surveyed prefer chicken?

enter your answer to the nearest tenth of a percent in the box.

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! )
