One of the most common forms of colorblindness is a sex-linked hereditary condition caused by a defect on the X chromosome (one of the two chromosomes that determine gender). It is known that colorblindness is much more prevalent in males than in females. Suppose that 6% of males are colorblind but only 0.75% of females are colorblind. In a certain population, 45% are male and 55% are female. A person is randomly selected from this population. (a) Find the probability that the person is colorblind. (b) Find the probability that the person is color blind given that the person is a male.
