Early reports put the failure rate at 20-30%, but most recent estimates I've seen put it at anywhere between 30-50% or possibly even higher. So assuming 50%, you really are pretty much flipping a coin since your odds of picking the right face of the coin are as good as getting a bum 360. But if you don't like that then we can assume 30% and say you have as much chance of picking two numbers on a six sided die and having them show up on a roll as you do getting a defective 360.
You won't get odds that good in Vegas.
