Helen is organising a party and she needs party plates and straws their 30 party place in a pack there are 120 straws in a pack she needs exactly same number of what is the minimum number of each pack she must buy

4 packs of party plates and one pack of straws.

Step-by-step explanation:

We have been given that there are 30 plates in a pack and 120 straws in a pack she needs exactly the same number of plates as straws.

To solve our given problem, we will convert find least common multiple of 30 and 120.

Multiples of 30: 30, 60, 90, 120,150,

Multiples of 120: 120, 240,...

We can see that least common multiple of 30 and 120 is 120.

Therefore, Helen should buy 4 packs of party plates and one pack of straws.

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! )
