In order to determine the economic viability of mining in a certain area, a mining company obtains samples of ore from the location and measures their zinc content and their iron content. Suppose that the random variable X and Y are the zinc and iron contents of the ore, respectively. Furthermore, suppose that their joint probability density function is f(x, y) = 6e-(2x+3y), х,у 20 Calculate the Cov(X,Y). Hence or otherwise comment on the dependency between X and Y.
