Question
Groups of adults are randomly selected and arranged in groups of three.
The random variable x is the number in the group who say that they
would feel comfortable in a self-driving vehicle. 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.
