Provide brief, but complete, answers to the following questions.(i)Why would one want to model some phenomenon as random but not others? For instance, an outcome of a coin toss is modeled as random but not the path of a projectile tossed into the air.(ii)What information completely characterizes, probabilistically speaking, a random variable? That is, having this information, one knows all one can possibly know about the nature of randomness.(iii)What would one want the relationship between population and sample moments to be, if any? Is this relationship even under one’s control?
