There are seven more ladies than men in the choir. if there are a total of nineteen choir members, how many ladies are there? how many men are in the choir

The answer is 13 ladies and 6 men

Step-by-step explanation:

The easiest way to get this is you have 19 people and take away 7 as they are ladies and you have 12 divide that by 2 getting you 6, then add the 7 ladies you took away at the start and add em to the 6 you have now. and thats how you get the answer.

Hope this helps and don't forget to hit that heart :)

b is the final answer! : )

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! )
