Arnold is studying the prevalence of three health risk factors, denoted by \mathrm{A}, \mathrm{B}, and \mathrm{C}, within a population of men. For each of the three factors, the probability that a randomly selected man in the population has only this risk factor (and none of the others) is 0.1. For any two of the three factors, the probability that a randomly selected man has exactly these two risk factors (but not the third) is 0.14 . The probability that a randomly selected man has all three risk factors, given that he has \mathrm{A} and \mathrm{B} is \frac{1}{3}. The probability that a man has none of the three risk factors given that he does not have risk factor \mathrm{A} is \frac{p}{q}, where p and q are relatively prime positive integers. Find p+q.
