A pair of dice are rolled and the sum on their upturned faces is recorded. What is the probability that the sum showing is 8, given that one die is showing a 5?
1 answer
If one die is 5, there is an equal probability that the second die will be 1 through 6, and that the total will be 6,7,8,9,10 or 11. So the answer is 1/6
