Step-by-step explanation:
To solve all possible probabilities, we have to find out the sample space of the experiment of rolling two dice simultaneously.
Sample space S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6)}

              {(5,1),(5,2),(5,3),(5,4),(5,5),(5,6)}
              {(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}
