If a dice is rolled three times, and six is the desired number, after two fails, what are the chances that at the third roll a six would appear? Is it 1/6 or bigger since the first two times it wasn't a six?

Each dice roll is independent of the outcome of the previous roll(s), hence the probability of the third roll being a '6' is 1/6.
