1. What is the difference between a discrete random variable and a continuous random variable? Provide an original example of each type of variable. 2. What makes the binomial distribution unique from other types of distributions? What are its characteristics? Provide a real-world example of a distribution of data that would be considered binomial. 3. Solve the following problem: About 30% of adults in United States have a college degree. Thus, the probability that a person has a college degree is p = 0.30. If N adults are randomly selected, find probabilities that a) exactly x out of selected N adults have a college degree, b) less than x out of selected N adults have a college degree, and c) greater than x out of selected N adults have college degree
