Question: See Exercise 4.35. Write an R function joint(i, j) for computing P(X = i, Y = j), for i = 0, 1; j = 1,

See Exercise 4.35. Write an R function joint(i, j) for computing P(X = i, Y = j), for i = 0, 1; j = 1, 2, 3. Use this function to compute the covariance and correlation of X and Y.

Data from Exercise 4.35.

Random variables X and Y have joint distribution P(X = i, Y = j) = c(i + j), for i = 0, 1; j = 1, 2, 3 for some constant c.
