You can put this solution on YOUR website! Two number cubes are rolled and the first cube shows a 3. Find the probability that you obtain a sum of 7.
---------
Rolling two dice gives 6*6=36 possible results.
Of those results these are the ones whose sum is 7:1,6) 2,5) 3,4) 4,3) 5,2) 6,1
So the probability = 6/36 or 1/6
