**SHORT ANSWER.** Write the word or phrase that best completes each statement or answers the question.Determine whether the following is a probability distribution. If not, identify the requirement that is not satisfied.4) In a certain town, 20% of adults have a college degree. The accompanying table describes the probability distribution for the number of adults (among 4 randomly selected adults) who have a college degree.| x | P(x) ||---|-------|| 0 | 0.4096 || 1 | 0.4096 || 2 | 0.1536 || 3 | 0.0256 || 4 | 0.0016 |4) ____________**Explanation of the Table:**- The table shows a probability distribution where `x` represents the number of adults with a college degree out of a randomly selected group of four adults.- `P(x)` represents the probability of exactly `x` adults having a college degree. To verify if this is a valid probability distribution:- Each probability must be between 0 and 1.- The probabilities must sum to 1.

Identify if the statement below is true or false: The sum of the probabilities in a discrete random probability distribution varies from distribution to distribution.
Determine whether the distribution is a discrete probability distribution. Is the distribution a discrete probability distribution? Why? Choose the correct answer below. O A. No, because some of the probabilities have values greater than 1 or less than 0. O B. Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive. O C. Yes, because the distribution is symmetric. O D. No, because the total probability is not equal to 1. CH X P(x) 0 0.16 1 0.21 0.26 0.21 0.16 3 4
