There are a number of questions similar to this, but I'm asking about rolling two dice twice, not one die two times. Or I guess you could think of it as 4 dice total, with each pair distinguishable.
So Person A rolls two dice (
d6) and gets some result between 2 and 12, with 7 being the most likely. Now Person B rolls two dice. What are the odds that Person B rolled the same number as Person A?
I've been trying to work this out for some time now, but it's been a while since I've taken Probability. (Do we have to do some conditional probability stuff here?)
