Households are randomly selected and partitioned into groups of four. For those groups, the random variable x is the number of households X P(x) with a printer. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a 0 0.023 probability distribution is not given, identify the requirements that are not satisfied. 0.145 2 0.340 3 0.354 4 0. 138 Does the table show a probability distribution? Select all that apply. A. Yes, the table shows a probability distribution. B. No, the numerical values of the random variable x are not associated with probabilities C. No, not every probability is between 0 and 1 inclusive D. No, the random variable x is categorical instead of numerical! E. No, the sum of all the probabilities is not equal to 1 Find the mean of the random variable x.
