When a standard pair of six sided dice are rolled, what is the probability of getting a 6? (Express your answer as a decimal rounded to the thousandsth place.)

Probability of getting a 6 is equal to
1 - the probability of not getting a six.
The probability of not getting a six on a single roll is 5/6. The probability of not getting a 6 for 2 rolls is (5/6)^2.
The probability of getting a six is

1 - (5/6)^2 = 11/36.
