Answer
$B'$
33
Work Step by Step
$B$: the numbers add to 4
The numbers do not add to 4: $B'$
$B'=${(1,1),(1,2),(1,4),(1,5),(1,6),(2,1),(2,3),(2,4),(2,5),(2,6),(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)}
(The first number is the red die, and the second is the green)
$n(B')=33$
