Well as I said what is the chance of getting at most one six when rolling two dice twenty times?

2. Relevant equations

I know the probability of getting one six in one roll with two dice is:

11/36

And not getting one is:

25/36

3. The attempt at a solution

Then I figured out that the probability of not getting a 6 in [itex]n[/itex] rolls is equal to:

[itex]P = 1 - (\frac{25}{36})^n[/itex]

So is that so?

And how do you calculate the proability of getting at most one 6 in twenty rolls?
