I apologize for last time. I made a slight error.
P[multiple of 3] = 1/3 = 12/36
P[sum of 8] = 5/36
However as I said last time (3,5) is not the only roll that satisfies both, we also have (6,2). This means we need to take in account the 2 cases out of 36 where both events take place.
So we calculate 12/36 + 5/36 - 2/36 = 5/12 which is our answer.
