Throwing a die twice gives 6×6=366\times6=36 equally likely ordered outcomes (i,j)(i,j) with i,j∈{1,…,6}i,j\in\{1,\ldots,6\}.

Each throw of a die has 6 possible outcomes: 1,2,3,4,5,61,2,3,4,5,6. When the die is thrown twice, the outcome is an ordered pair (result of first throw, result of second throw), so the total number of outcomes is 6×6=366\times6=36.

The sample space is:

S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),S = \{(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),

(2,1),(2,2),…,(2,6),(2,1),(2,2),\ldots,(2,6),

⋮\vdots …
