Let us see the possible results for the sum of two rolled dice.
Let us highlight in yellow the results in which the sum of two dice rolled is greater than 6. That is, the outcomes in E.
Therefore, the white combinations in the table are the outcomes in the complement of event E:
![E^c=\lbrace(1,1),(1,2),(1,3),(1,4),(1,5),(2,1),(2,2),(2,3),(2,4),(3,1),(3,2),(3,3),(4,1),(4,2),(5,1)\rbrace]()
