    out of the 36 ways to come out; there are only 4 ways that matter so 4 out of 36 seems more reasonable right?

    how many ways are divisible by 5 or 6 or both? 5 and 10 are divisible by 5 6 and 12 are divisible by 6

    when you roll a dice twice; you only get the options 1 thru 6 as a face value; the lowest sum is 2 and the highest is 12 gotta keep them between 2 and 12 right?

    so 36 total chances; 6*6 = 36 ways the only combos available for a 9 are to roll: 6,3 3,6 5,4 4,5 that is only 4 ways out of 36 to get a sum of 9 right?

    so P(A) = 4/36 = 1/9
