Groups of adults are randomly selected and arranged in groups of three. x The random variable x is the number in the group who say that they would 00.362 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 20.182 3 0.024 a. Yes, the table shows a probability distribution. b. No, not every probability is between 0 and 1 inclusive c. No, the random variable x is categorical instead of numerical d. No, the random variable x's number values are not associated with probabilities. e. No, the sum of all the probabilities is not equal to 1 Find the mean of the random variable x.
