If you want to know what the chances are that at least on of the die will come up six, you add the probabilities together. So, 1/6 + 1/6 = 1/3. But, if you want to know what the chances are of both die rolling 6, you multiply the probabilites.p 1/6 × 1/6 = 1/36.
Just a quibble: if you roll two dice, the probability that at least one will be a 6 is 1-(5/6)*(5/6)=1-25/36=11/36. This is NOT 1/3. To correctly compute this probability, you have to first find the probability that *neither* got a 6 (i.e, both got 1 to 5) and then subtract that from 1 (the negation).
Alternatively, you can compute it via 1/6 + 1/6 - (1/6)*(1/6) = 1/3 - 1/36 =11/36. In your calculation, you neglected the probability of both getting a 6, thereby overestimating the probability slightly.
