I'm having trouble with this probability question.

"Find the probability of rolling an even sum or a sum greater than nine when a pair of dice is rolled."

So P(A)= even sum when dice rolled

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

P(B)= sum greater than nine when dice rolled

(4,6) (5,5) (5,6) (6,6)

P(A or B) (A and B)

..and now I'm stuck, I don't know if I'm even doing it right.

help?
