point(s) possible Households are randomly selected and partitioned into groups of four For those groups, the random variable x is the number of households with X P(x) D a printer. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a 0 0 025 probability distribution is not given, identify the requirements that are not satisfied 0.145 2 0 338 3 0.357 4 0 135 ew by 2 We Does the table show a probability distribution?
