Households are randomly selected and partitioned into groups of four. For those groups, the random variable x is the number of households with a printer. 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. Does the table show a probability distribution? Select all that apply. A. Yes, the table shows a probability distribution. B. No, the random variable x is categorical instead of numerical. C. No, the sum of all the probabilities is not equal to 1. D. No, the numerical values of the random variable x are not associated with probabilities. E. No, not every probability is between 0 and 1 inclusive. Find the mean of the random variable x.
