When conducting research on color blindness in males, a researcher
forms random groups with five males in each group. The random variable
x is the number of males in the group who have a form of color blindness.
Determine whether a probability distribution is given. If a probability
distribution is given, find its mean and standard deviation. If a probability
distribution is not given, identify the requirements that are not satisfied.
