TITLE: If you roll a fair six sided die twice, what's the probability that you get the same number both times?
QUESTION [6 upvotes]: So I know that rolling a fair six-sided die twice would mean the total possible outcomes would be 36, and rolling the same number twice would be 2/36 or 1/18, but I feel like that's wrong. What am I doing that isn't right?

REPLY [6 votes]: The first roll doesn't matter. It only sets a target. The chances of hitting a target in one roll are one in SIX, not one in three. You could have someone call out a number for the target. That doesn't matter.
