et Y be a random variable denoting the miles driven per year by Tracy and m denote the sample mean of the maintenance cost per mile that you found in the previous task. Define Z = mXY. Z is a random variable representing the maintenance cost through the time that Tracy will keep the car. Assume that X and Y are independent random variables, so that for example P(X = 2, Y = 9,000) = P(X = 2) P(Y = 9,000). Create a data frame for the probability table of Z and show your frame on the Word document. Using the probability table, find the probability that the maintenance cost will be less than $3,000. In summary, based on your results, what would you recommend to Tracy
