Use the theoretical probability formula to solve the problem. Express the probability as a simplified fraction.This problem deals with eye color, an inherited trait. For purposes of this problem, assume that only two eye colors are possible, brown and blue. We use b to represent a blue eye gene and B a brown eye gene. If any B genes are present, the person will have brown eyes. The table shows the four possibilities for the children of two brown-eyed (Bb) parents. Second Parent B bFirst Parent B BB Bb b Bb bbFind the probability that these parents give birth to a child who has blue eyes (bb).
