Total no. of outcomes = 6² = 36

1) probability = 18/36 = 3/6=1/2

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

2) probability = 27/36 = 9/12=3/4

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