11 , 13 , 15 , 22 , 24 , 26 , 31 , 33 , 35 , 42 , 44 , 46 , 51 , 53 , 55 , 62 , 64 , 66 , Total =  18 Even sums.
14 , 23 , 32 , 41 , 46 , 55 , 64 , Total =  7 - sums that are multiples of 5

Probability =[18 + 7] / 6^2 = 25 / 36

 

 

12 , 15 , 21 , 24 , 33 , 36 , 42 , 45 , 51 , 54 , 63 , 66 , Total =  12 - sums that are multiples of 3.
13 , 22 , 26 , 31 , 35 , 44 , 53 , 62 , 66 , Total =9 - sums that are multiples of 4

Probability =[12 + 9] / 6^2 = 21 / 36 = 7 / 12
