Decide whether you can use the normal distribution to approximate the binomial distribution. If you​ can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you​ cannot, explain why and use the binomial distribution to find the indicated probabilities. A survey of adults found that 79​% of those who text on cell phones receive spam or unwanted messages. You randomly select 100 adults who text on cell phones. Complete parts​ (a) through​ (d). Determine whether a normal distribution can be used to approximate the binomial distribution. Choose the correct answer below. A. ​No, because np<5. B. ​Yes, because both np≥5 and nq≥5. Your answer is correct. C. ​No, because nq<5. ​(a) Find the probability that the number of people who receive spam or unwanted
