Let X = the number of customers that bought a box containing an extra donut.Part A: Is X a binomial random variable? Explain. (3 points)Part B: What is the mean and standard deviation of X? Provide an interpretation for each value in context. (4 points)Part C: Two of the eight customers buy a box of donuts with an extra donut. Is the shop’s claim accurate?
