If event E is defined as the event that "the sum of two rolled dice is less than or equal to 4."
Then the complement to E will represent all remaining outcomes, that is that "the sum of two rolled dice is greater than 4"
If the die is numbered from 1 to 6, the possible combinations are:
Add all combinations whose sums are greater than 4, without repeating combinations:
