In a survey conducted by a reputable research​ organization, more than​ 2,000 smartphone users were asked how often the applications​ (apps) they downloaded on their cell phones were not working correctly. Responses were recorded as 1=​Frequently, 2=​Occasionally, 3=​Rarely, and 4=Never. The probability distribution for the numerical​ response, x, is provided in the accompanying table. Complete parts a through c below. a. Verify that the properties of a probability distribution for a discrete random variable are satisfied. Select all that apply.
A. The probabilities are all given to the same number of decimal places.
B. The sum of all the probabilities is 1.
C. The values of x are listed in a meaningful order.
D. There are at least three different values of x.
E. There are at most ten different values of x.
F. Each value of x is an integer.
G. The values of x have practical meaning in the context of the situation.
H. Each probability is nonnegative.
