Suppose there are 300 cards in a box numbered 1 through 300.
Therefore, the number of each card has one, two, or three digits. A
card is drawn at random from the box. Suppose that the number on
the card has X digits of which Y are 0. Suppose we would like to
know whether X and Y are correlated, negatively correlated, or
uncorrelated. Determine Cov(X,Y)Cov(X,Y) and ρ(X,Y)ρ(X,Y), hence...
