Zegroes, there is a word for people like you  :)

Both answers are correct :)

You need more information than that.  :)

Maybe 3 people have 2peices  

and 2 people have 1 peice

I think that Zegroes answer is correct although I do not understand the explanation that he has given.   

The number of ways that 3 people can be chosen from 12 is   12C3 = 220

There are 9 people left.  The number of ways that 4 people can be chosen from these is 9C4 = 126

There are 5 people left.  The number of ways that 5 people can be chosen from these is 5C5 = 1

so the number of possible committees is 220 * 126 * 1 = 27720

you can choose in a different order if you wish but the answer will be the same.    

with the calculator on the home page

which ratio is the same as 40%

Ratio can be used in different ways so there are really 2 valid answers for this

Say you have a mixture that is 40% active ingredient and the other 60% is water

you could say that the ratio of active ingredient to the total is  40:100 which simplifies to 2:5

OR

you could say that the ratio of active ingredient to water is  40:60 which simplifies to 2:3

Are you going to shoot us with an arrow Happy?

You'll have to think of something different for CPhill.  He is just dust so it won't 'impact' him.  LOL  

Hi Zegroes

I can see that you have made an impression on the younger, newer set already.  Perhaps you are a bit of a dinosaur yourself these days.

It means log base e

e is just a special number like pi is a special number.

A log is an expoment or power.

You"ll learn this stuff later :)
