A recent survey reported that 49% of adults in a certain country own tablets. Using the binomial distribution, complete parts (a) through (e) below. a. What is the probability that out of the next six adults surveyed, exactly four will own a tablet? The probability is (Type an integer or a decimal. Round to four decimal places as needed.). b. What is the probability that out of the next six adults surveyed, all six will own a tablet? The probability is. (Type an integer or a decimal. Round to four decimal places as needed.) c. What is the probability that out of the next six adults surveyed, at least four will own a tablet? The probability is (Type an integer or a decimal. Round to four decimal places as needed.) d. What are the mean and standard deviation of the number of adults who will own a tablet in a survey of six adults? The mean number of adults who own tablets out of six surveyed is (Type an integer or a decimal. Round to four decimal places as needed.) The standard deviation of the number of adults who own tablets out of six surveyed is (Type an integer or a decimal. Round to four decimal places as needed.)
