Farkle problem (Probability)
If you were going to roll 6 dice, what is the probability of getting an all-6?
I am thinking of it as 1/36 chance, but I don't know how to get the chance.
I am just a third grade student in the Philippines, and our mathematics teacher did not discuss us the concept of probability.
Please help me!

Re: Farkle problem (Probability)
There are six faces in one die.
Therefore, the chance of any of them occuring once is 1/6
Now, suppose there are two dice with 6 faces each
Now there can be 36 ways of the outcome
E.g, (1,1) (1,2) ... (2,1) (2,2) (2,3) .... (6,5) (6,6)
Therefore the chance of getting two sixes is 1/36
You can also get it by multiplying (1/6)*(1/6)

For six dice it will be
You work out the probability of each event (1/6) and, if they are independent, mutliply the porbabilities.

Agnishom, when all dices face a 6, not only 2.

Hi julianthemath;
He was showing you how you can reason about it for six by showing two.
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Found it out. It's 1/46656, found it in Yahoo! Answers.

Hi julianthemath;
You can not always trust yahoo answers. In this case they were right but the question was already answered up above and by more reliable people.
