When rolling a certain unfair six-sided die with faces numbered , and , the probability of obtaining face is greater than , the probability of obtaining the face opposite is less than , the probability of obtaining any one of the other four faces is , and the sum of the numbers on opposite faces is . When two such dice are rolled, the probability of obtaining a sum of is . Given that the probability of obtaining face is , where and are relatively prime positive integers, find .
