A sociologist randomly selects single adults for different groups of three,
and the random variable x is the number in the group who say that the
most fun way to flirt is in person. 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.
