What is the probability of rolling a number less than or equal to eight with the sum of two dice, given that at least one of the dice must show a 6?

Answer:
4/11
Step-by-step explanation:
Outcomes that meet your requirement are
(1, 6), (2, 6), (6, 1), (6, 2)
for a total of 4 favorable outcomes.
There are 11 outcomes in which one die shows a 6.
So your probability would be 4/11.
