In a village 20% children were suffering from malaria. A blood test ordinarily reports positive in 80% cases if the patient was infected by malaria and in 60% cases reports negative if the patient was not infected by malaria. A child was selected at random from the village and the blood test report was positive. Then what is the probability that he is infected by malaria ?
