A poll found that 35% of adults do not work at all while on summer vacation. In a random sample of 7 adults, let x represent the number who do not work during summer vacation. Complete parts a through e. a. For this experiment, define the event that represents a "success." Choose the correct answer below. O Adults working during summer vacation ✔Adults not working during summer vacation b. Explain why x is (approximately) a binomial random variable. Choose the correct answer below. O A. There are three possible outcomes on each trial. OB. The experiment consists of only identical trials. OC. The trials are not independent. D. The experiment consists of identical trials, there are only two possible outcomes on each trial (works or does not work), and the trials are independent. c. Give the value of p for this binomial experiment. p= 0.35 d. Find P(x = 3). P(x= 3) = (Round to four decimal places as needed.)
