In a random sample of 25 survey respondents, consider the number of people who take part in sports and outdoor activities regularly and go on short distance walks as one of their outdoor activities.

a. Explain why is (approximately) a binomial random variable.

b. Use the rules of probability to determine the value of for this binomial experiment.

c. Assume Find the probability that at least 10 of the 25 survey respondents take part in sports and outdoor activities regularly and go on short distance walks as one of their outdoor activities.
