When rolling a die, is this an example of a discrete or continuous random variable? Explain your reasoning.Rolling a die is a discrete random variable. The random variable can take values like X = 1,2,3,4,5,6 which will always be number and can never be 1.0001 or 1.99 etc.|2. Calculate the mean and standard deviation of the probability distribution created by rolling a die. Either show work or explain how your answer was calculated.Mean: 3.5Standard deviati
