In a survey, cell phone users were asked which ear they use to hear their cell phone, andthe table is based on their responses. Determine whether a probability distribution isgiven. If a probability distribution is given, find its mean and standard deviation. If aprobability distribution is not given, identify the requirements that are not satisfied.LeftRightNopreferenceDoes the table show a probability distribution? Select all that apply.A. Yes, the table shows a probability distribution.B.No, the sum of all the probabilities is not equal to 1.C.No, not every probability is between 0 and 1 inclusive.D.No, the random variable x is categorical instead of numerical.E.

We are interested in analyzing data related to college football. Use S to denote the team is in the SEC and use W to denote a team has a winning season. The probability that a team is in the SEC in the data set is 5.5%. The probability that a team has a winning season is 52.5%. The probability that a team is in the SEC and has a winning season is 3.55%. What percentage of teams are in the SEC or had a winning season? b. What percentage of people teams are in the SEC and did NOT have a winning season? Given a team had a winning season, what is the probability that they are in the SEC? а. с.
