A sociologist randomly selects single adults for different groups of three, and the random variable x is the number in the group who say that the most fun way to flirt is in person. 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. P(x) 0.085 0.343 0.409 0.163 3 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. O C. No, not every probability is between 0 and 1 inclusive. O D. No, the sum of all the probabilities is not equal to 1. DE. No, the random variable x's number values are not associated with probabilities. Find the mean of the random variable x.
