You have one fair die and one weighted die. If the probability of rolling a sum of 4 with both dice is 1/12, and the probability of rolling a 4 with the weighted die alone is 1/10, then the probability of rolling a sum of 11 with both dice is?

Are we assuming that these are normal, six-sided dice numbered 1-6, with the only oddity being that one is not fair?
