Answer:

7/12.

Step-by-step explanation:

The total possible outcomes = 6*6 = 36.

Possible outcomes for a total  8 or greater are :

2,6  6,2  3,5   5,3  3,6  6,3   4,4  4,5  5,4  4,6  6,4  5,5,  5,6  6,5  6,6 = 15.

So the number of outcomes for a sum < 8 = 36 - 15 = 21.

Answer is 21/36 = 7/12.
