Question

Two dice are rolled to determine the sum. What is the probability that the sum on both dice is 7, given that exactly one die turned up a 5?

Answer 1

1/6, the odds of rolling a 2 on one die.

Answer 2

HI!!

Answer 3

not to argue with @robtobey but that is the probability you get a seven, not the "odds" in any case the question tells you that one of the die is 9
we can list all of those, it is not that many

Answer 4

here is the list of rolls where one die is a 5
\[(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(1,5),(2,5),(3,5),(4,5),(6,5)\]

Answer 5

i count eleven
out of those, how many add up to 7?
