problem with calculation of probability

Post icon  Posted 07 December 2009 - 09:08 AM

Hey,

I have got a problem concerning calculation of probability.
Here it is:
I have got 6 dices.
Off course the change of throwing 1 with a single dice is 1/6, just like every number.
When I throw 6 dices, I know there are 6^6=46656 possibilities.
I know that some of these possibilities are in it more than once, but that doesn't matter.
The lowest total I can get is 6*1=6, the highest is 6*6=36.
Now what I need to know is how to calculate:
the change of throwing a total of 6 (1/46656 off course)
the change of throwing a total of 7
the change of throwing a total of 8
...
...
...
the change of throwing a total of 36 (1/46656 off course)

If someone could tell me how to calculate all of this in a simple way,
that would be highly appreciated.

This is math problem, not a programming problem and you have to show your code before we help, it's the policy of D.I.C.
***
the change of throwing a total of 7, just make the cases, it is like the following:
(select one dice from 6)*(1/6) -> the chance for having one dice with a value of 2
(select five dices from 5)*(1/6)^5 -> the chance for having 5 dices with value of 1
...
this was just an example for how to solve this, for the code, we cannot write it for you, you have to find the way to write it.

I am sorry for putting this question in the wrong category.
It's just that I use this site for the first time today.
I am busy doing programming on C++, but first I need to solve this.
That's why the question is put into the C/C++-category.
Also I didn't ask for a code, I don't need someone to just give me the answer.
I only need to know how to calculate such possibilities.
Thanks anyway.
