Answer
Sample Space = {(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) }
Event: Getting a sum of 4 or 5 = {(1,3), (2,2), (3,1), (2, 3), (1, 4), (4, 1), (2, 3)}
No. of outcomes in event = 7
