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.

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)

Re: Farkle problem (Probability)

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.

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.
