Answer: The probability that the sum is 11 given that the first cube shows a 6.
Explanation:
By the definition of conditional probability,
If we have two probabilities A and B where A and B are dependent variable,
If we have to find the probability of occurring the event A when B is given ,
Then we find P(A/B).
Here A is the event that there is 6 in first die when we rolled two dice,
And, B is the event that the sum of the numbers shown in both die is 11,
Hence, P(A/B) shows, The probability that the sum is 11 given that the first cube shows a 6.
