Yo what's the probability of when you have 2 dice rolling an infinite amount of times that a 2, 3, 5, or 12 will come up?

If you mean, what's the probability that the sum of two fair dice rolled randomly ever equal one of those numbers, the answer is 1.

umm... no I didn't mean that. I meant what's the chance that those numbers come up at any point when rolled. Don't worry about it though, I was drunk playing Settler's of Catan and wanted to know, was too drunk to quickly write a program but I'm sober now and wrote a python program to roll two dice 100,000 times then get the average that any of those three numbers show up. The answer is ~22%.

You can do it with straight probability. P(roll=2 or 3 or 5 or 12) = P(roll=2) + P(roll=3) + P(roll=5) + P(roll=12) = 1/36 + 2/36 + 4/36 + 1/36 = 8/36 = 22.22%.
