Correct Answer - Option 2 : 5 / 36

Possible Outcome:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (3,1) (3,2) (3,3) (3,4) (3,5) (3,6) (4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (5,1) (5,2) (5,3) (5,4) (5,5) (5,6) (6,1) (6,2) (6,3) (6,4) (6,5) (6,6) are the total numbers we get when we throw a pair of dice that is 36. 

Expected Outcome:

The probability of getting a sum of 8:

(2,6) (3,5) (4,4) (5,3) (6,2) are the 5 pairs which upon adding we get 8.

Probability is the ratio of the number of expected outcomes to the number of all possible outcomes.

Therefore, 5/36 is the answer.
