A human gene carries a certain disease from the mother to the child with a probability rate of 51%. That is, there is a 51% chance that the child becomes infected with the disease. Suppose a female carrier of the gene has five children. Assume that the infections of the five children are independent of one another. Find the probability that at least one of the children gets the disease from their mother.  Round to three decimal places.
