Probability from a Sample Space. In Exercises 3742, use the given sample space orconstruct the required sample space to find the indicated probability. X-Linked Genetic Disease Men have XY (or YX) chromosomes and women have XXchromosomes. X-linked recessive genetic diseases (such as juvenile retinoschisis) occur whenthere is a defective X chromosome that occurs without a paired X chromosome that is good.In the following, represent a defective X chromosome with lowercase x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xxwill not have the disease. Each parent contributes one of the chromosomes to the child.a. If a father has the defective x chromosome and the mother has good XX chromosomes,what is the probability that a son will inherit the disease?b. If a father has the defective x chromosome and the mother has good XX chromosomes,what is the probability that a daughter will inherit the disease?c. If a mother has one defective x chromosome and one good X chromosome and the fatherhas good XY chromosomes, what is the probability that a son will inherit the disease?d. If a mother has one defective x chromosome and one good X chromosome and the fatherhas good XY chromosomes, what is the probability that a daughter will inherit the disease?\
