Suppose a poll taken a few years ago found 75% of parents spank their children. Now suppose a random sample of 20 parents is obtained and the number of parents who spank their children is recorded. Find the probability that 8 of the 20 parents spank their children. Round to five decimal places. Find the probability of 10 or fewer parents in this sample spank their children. Round to 5 decimal places. What are all the possible value of x for this binomial experiment?
