Final answer:
The probability of rolling a 6 on either the red or blue die when rolling 2 dice is 11/36.
Step-by-step explanation:
When rolling two dice, one red and one blue, there are a total of 36 possible outcomes since each die has 6 faces. To find the probability of rolling a 6 on either the red or blue die, we need to determine the number of favorable outcomes. In this case, there are 11 favorable outcomes (5 on the red die and 6 on the blue die, or 6 on the red die and 5 on the blue die).
Therefore, the probability of rolling a 6 on the red or blue die is 11/36.
