A pair of dice is tossed twice.

Find the probability that both rolls give a sum of 8. (Enter your probability as a fraction.)

There are 36 possible outcomes when tossing two dice (6 possibilities for the first dice and 6 possibilities for the second dice).

To find the number of outcomes where the sum of both rolls is 8, we can list them out:
(2,6), (3,5), (4,4), (5,3), (6,2)

There are 5 favorable outcomes.

Therefore, the probability of both rolls giving a sum of 8 is 5/36.
