For those groups, the x P(x) random variable x is the number of households with a printer. Determine whether a probability 0 0.027 distribution is given. If a probability distribution is given, find its mean and standard deviation. If a 1 0. 144 probability distribution is not given, identify the requirements that are not satisfied. 2 0.342 3 0.353 4 0.134 Find the mean of the random variable x.
