A teacher wants to sent 5 students to the library each day. There are 22 students in the class. How many ways can she choose 5 students to go to the library on the first day?

There are 26 334 ways.

Step-by-step explanation:

Using Combination Rule because the question say choosing 5 students to go where the arrangement or order does not matters.

22C5 = 26 334

*nCr, n is a number of objects and r is the number of spaces/seats

(Correct me if I am wrong)

the statemwnt is the company makes small and large snow cone cups.

large=it holds more then the small

small=it holds less then the large

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! )
