P.38 Color Blindness in Men and Women The most common form of color blindness is an inability to distinguish red from green. However, this particular form of color blindness is much more common in men than in women (this is because the genes corresponding to the red and green receptors are located on the X- chromosome). Approximately 7% of American men and 0.4% of American women are red-green color-blind. (a) If an American male is selected at random, what is the probability that he is red-green color-blind? (b) If an American female is selected at random, what is the probability that she is NOT red-green color-blind? (c) If one man and one woman are selected at random, what is the probability that neither are red-green color-blind? (d) If one man and one woman are selected at random, what is the probability that at least one of them is red-green color-blind?
