If I'm rolling 10D6 what's the chances of rolling triple 3?
Thanks
Sorry, I mean triple 1 (although I know its the same) Or what's the chance of rolling dobble ones?
I haven't completely figured out to use it, but there's a dice probability calculator here: http://anydice.com/ (http://anydice.com/)
Using the string:
output 10d6 named "1, 1, 1, x, x, x, x, x, x, x" - (requiring 1's on 3 dice, and no requirements on the other 7)
gives a result of around 7%? Whether any of that is correct though, is a whole other matter!
:D
My mistake, Leon probably has it right.
Yeah, can't quite get that program to work. 7% sound right to me.
Thanks
The probability of rolling 3 or more 1s on 10D6 would be higher than that though.
Glad you read the question properly LH.
I certainly didn't the first TWICE !! :-[
And now my comment has jumped in on top of yours.....AAAARGH !! :-[ :-[

There are 60466176 different rolls with 10 x d6 - most will duplicate at least nine other results (9 x 1 + 1 x 6, same as 1, 6, 8x 1 etc)
I know that there are 36 combos where the first dice is one and 2 others are one
28 where die 2 is 1 (excluding one of the others being die 1)
21 where die 3 is 1 (Ex others being dice 1 or 2)
15 die 4
10 die 5
6 die 6
3 die 7
1 die 8 is 1, no duplicates
120 chances of EXACTLY 3 ones
Hmmm Excell and open office have functions to calc this - will look later
This is starting to make my brain hurt lots ! ;D :-/
Think there must be lots more combinations than 120 for 3 ones LH. ?
True...there would be 36 combos where the first dice is one....and two others are ones as well....But only if we ignore the 5 (numbers 2 to 6) possible variations on each of the other seven dice. 8-}
Don't we need to take those into account as well ?

I think one of us should grab a handful of dice, a pen and a piece of paper, and get rolling!
What ?......
No....Write all the combinations down....All sixty and a half million of them.
I'll start....
1,1,1,1,1,1,1,1,1,1.....
Cheers - Phil ;) ;D
I think this post is in the wrong section.
This maths is hardly "FUN STUFF" unless of course you havve masochistic tendancies ;D ;D
Or the original poster rofls about all of us actually rolling dices like there is no tomorrow...
;D

Using Pascall's Triangle you can work out that the probability of rolling exactly three ones on ten D6s is
120 q7 * p3
Where p is probability of rolling a 1 = 1/6
And q is the probability of rolling a number other than a 1 = 5/6
That's about 2.15%
