induviduals who have a particular gene have a .72 probability of contracting a certain disease suppose that 526 induviduals with the gene participate in a lifetime study what is the standard deviation of the number of people who eventually contract the disease?
I need to solve this question using excel. Suppose that individuals with a certain gene have 70% probability of eventually contracting a certain disease. If 100 individuals with the gene participate in lifetime study, what is the probability that 70 or more of them eventually contract the disease?
