    Question: A student appears for a test in mathematics, physics, and chemistry. The student is successful if                       he passes either in mathematics and physics or in mathematics and chemistry. The probabilities                       of the student passing in mathematics, physics, and chemistry are m, n and 1/2 respectively.                             If the probability that the student is successful is 1/2 then find the relation between m and n.
