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 77​% say their favorite sport is auto racing. You randomly select 600 adults and ask them to name their favorite sport. (c) Find the probability that the number of people who say auto racing is their favorite sport is between 38 and 45​,inclusive
