A certain gene is carried by 20% of women and 80%\nof men. The chance that a child gets the gene is:\n• 50% if only mother has it\n• 40% if only father has it\n• 60% if both parents have it\nWhat is the probability that the child (still unborn)\nhas the gene?

A human gene carries a certain disease from the mother to the child with a probability rate of 40%. That is, there is a 40% chance that the child becomes infected with the disease. Suppose a female carrier of the gene has three children. Assume that the infections of the three children are independent of one another. Find the probability that at least one of the children get the disease from their mother.

The probability that a person will show a certain gene-transmitted trait is 0.8 if the father shows the trait and 0.06 if the father doesn't show the trait. Suppose that the children in a certain community come from families in 25% of which the father shows the trait. Given that a child shows the trait, what is the probability that her father shows the trait?

A human gene carries a certain disease from a mother to her child with a probability rate of 0.41. That is, there is a 41% chance that the child becomes infected with the disease. Suppose a female carrier of the gene has five children. Assume that the infections, or lack thereof, are independent of one another. Find the probability that all five of the children get the disease from their mother.
