possible College students are randomly selected and arranged in groups of three The random variable x is the number in the group who say that they take one or more online courses 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 Does 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 No the numerical values of the random variable x are not associated with probabilities OA Find the mean of the random variable x Select the correct choice below and if necessary fill in the answer box to complete your choice P students Round to one decimal place as needed OB The table does not show a probability distribution www OA students X P x 0 0 106 1 0 359 2 0 394 3 0 141 Find the standard deviation of the random variable x Select the correct choice below and if necessary fill in the answer box to complete your choice Round to one decimal place as needed OB The table does not show a probability distribution
