This probably should be very easy but i am not good at probability.
Given a fair die, what is the probability of rolling at least 2 sixes if the die is rolled 12 times.
I have tried a little bit, and this is what I have.
First of all, i know the universe is equal to 6^12. And the hint is that it is easier to compute the probability of the event not happening.
If A is the event of getting at least 2 sixes, B is getting 1 or no sixes.
P(B)=?? Therefore, P(A)=1-P(B)
Thanks for any help.
