Quizplus · Accepted Answer

There are 36 possible outcomes when rolling two dice (6 outcomes for each die), and of those outcomes, there are 6 outcomes that result in a sum of 7 (1+6, 2+5, 3+4, 4+3, 5+2, 6+1). There are also 5 outcomes that result in a sum of 8 (2+6, 3+5, 4+4, 5+3, 6+2) and 4 outcomes that result in a sum of 9 (3+6, 4+5, 5+4, 6+3). Therefore, the probability of rolling a sum of 7 or more is (6+5+4)/36, which simplifies to 15/36, or 5/12.
