If you roll two fair six-sided dice, what is the probability that at least one die shows a 3?

- - Two fair dice can land in 36 possible ways. (6 ways each).

- - The successful tosses are

3 ... (not 3)

(not 3) ... 3

and 3 ... 3

Three of the 36 possible outcomes are successful.

- - The probability of a successful toss is

(3) / (36) = 1/12 = (8 and 1/3) %.
