Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 133 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Find the probability that exactly 33 votedThe probability that exactly 33 of 133 eligible voters voted is _______________________. (Round to 4 dec places as needed.)

In a study, it was found that 42.5% of the population drink soda at least once a day. You randomly select 8 people. Let X be the number of people in the sample that drink soda at least once a day.Then X has what distribution?

Question 9 Based on a​ poll, among adults who regret getting​ tattoos, 17% say that they were too young when they got their tattoos. Assume that 8 adults who regret getting tattoos are randomly​ selected, and find the indicated probability. 1. Find the probability that none of the selected adults say that they were too young to get  tattoos  2. Find the probability that exactly one of the selected adults says that he or she was too young to get tattoos. 3.  Find the probability that the number of selected adults saying they were too young is 0 or 1.
