The probability of rolling a total of 8 can be calculated by finding the combinations that add up to 8: (2,6), (3,5), (4,4), (5,3), (6,2), which are 5 combinations. The probability of rolling doubles (same up faces) is 6 combinations (1,1), (2,2), (3,3), (4,4), (5,5), (6,6). However, the combination (4,4) is counted in both scenarios, so we have a total of 10 unique combinations that satisfy the conditions. Since there are 36 possible outcomes when rolling two dice (6 faces per die), the probability is 10/36, which simplifies to approximately 0.28 when rounded to the nearest hundredth.
