Short Answer
6. The theoretical probability that a man will have some form of color blindness is 8%, whereas the theoretical
probability of a woman having color blindness is 0.5%.
a. If you have a group of 700 men, predict how many of them will be color blind.
b. If you have a group of 400 women, predict how many of them will be color blind.
c. If you combine both groups and pick one person at random, what is the probability that
person will be color blind? Write the probability as a percent and round to the nearest
tenth of a percent if necessary.
