Q3 An orthopedic physician's practice considers the number of errors in a bill and the number of X-rays listed on the bill. There may or may not be a relationship between these random variables. Let the random variables X and Y denote the number of errors and the number of X-rays on a bill, respectively. Assume that the joint probability distribution of X and Y is defined by fxx (x, y) and it is given below, determine the covariance and correlation.
