1. Studies in population genetics indicate that 39% of the available genes for determining the Rh blood factor are negative. Rh negative blood occurs if and only if the individual has two negative genes. One gene is inherited independently from each parent. What is the probability that a randomly selected individual will have Rh negative blood?
2. An individual's blood group (A, B, AB, 0) is independent of the Rh classification. Find the probability that a randomly selected individual will have AB negative blood.
