You can put this solution on YOUR website! Since the sum could be 2,3,4,5,6,or 7, find the probability for each of those. Sum=2, 1 outcome/21 outcomes,
  Sum=3, 2 outcome/21 outcomes,
  Sum=4, 3 outcome/21 outcomes,
  Sum=5, 4 outcome/21 outcomes,
  Sum=6, 5 outcome/21 outcomes,
  Sum=7, 6 outcome/21 outcomes,
