Final answer:
The probability of getting an 11 when rolling two standard six-sided dice is 1/18.
Step-by-step explanation:
To find the probability of getting an 11 when rolling two standard six-sided dice and adding the numbers, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
The favorable outcomes are when we roll a 5 on the first die and a 6 on the second die, or when we roll a 6 on the first die and a 5 on the second die. So there are 2 favorable outcomes.
The total number of possible outcomes is the product of the number of outcomes for each die, which is 6 x 6 = 36.
Therefore, the probability of getting an 11 is 2/36, which simplifies to 1/18.
