tutor3 : Hello Student, May I help you with your Math problems?
student : Sickle-cell anemia is a hereditary medical condition affecting red blood cells that is thought to protect against malaria, a debilitating parasitic infection of the liver and blood.
That would explain why the sickle-cell trait is found in people who originally came from Africa, where malaria is widespread.
A study in Africa tested 543 children for the sickle-cell trait and also for malaria infection.
In all, 25% of the children had sickle-cell and 6.6% of the children had both sickle-cell and malaria. Overall, 34.6% of the children had malaria. What is the probability that a given child has neither malaria nor sickle-cell?
Give your answer in percents as a whole number.
