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!

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.

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.
