To find the probability of rolling a 6 or a 7 with two dice, we count the number of outcomes that result in each total. For a total of 6, the combinations are (1,5), (2,4), (3,3), (4,2), and (5,1), which gives us 5 outcomes. For a total of 7, the combinations are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1), which gives us 6 outcomes. Adding these together, we get 11 possible outcomes. Since there are 36 possible outcomes when rolling two dice (6 sides on the first die times 6 sides on the second die), the probability is 11/36.
