Let 1,2,3,4,5,6 denote the event the respective numbers comes when the die is thrown
The total number of sample space = (6 x 6) = 36
We define the possible outcomes by an ordered set (x, y)
where,
x denotes the digit occurring on the first die
y denotes the digit occurring on the second die
The sample spaces
S = {(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)}
