Need help all of these three questions The last question has a part a part which is if the table does not show a probability distribution. Need help

In a survey, cell phone users were asked which ear they use to hear their cell phone, and the table is based on their responses. Determine P(x) whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability Left 0.6357 leeks distribution is not given, identify the requirements that are not satisfied. Right 0.3043 No 0.060 oo preference . . . . 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, the sum of all the probabilities is not equal to 1. D. No, not every probability is between 0 and 1 inclusive. E. No, the random variable x is categorical instead of numerical. urc Find the mean of the random variable x.
